IEEE Building Automotive Black-Box Standard
An anonymous submitter writes: "According to EE Times, the IEEE is working to develop an automotive black-box standard similar to what airplanes have. Forget Acme Rent-A-Car in Connecticut - get ready to have your insurance company jack your rates for going over 65mph."
Why on the internet? Even airplane black boxes don't appear to be hooked up for communication of any kind, otherwise people wouldn't be so concerned with finding them after a crash.
Why can't this be a similarly autonomous data-gathering device? If there's any need for it outisde of crash data recovery, clearly there's a different purpose involved.

They can install one in my car...
...when they pry the steering wheel from my cold, dead hands.
Seriously, though, in my state (and most others) insurance is mandatory. Now, suppose that in order to get insurance one needs to install this box. Suddenly, the box is mandatory, if not explicitly so...
Once again, perhaps the best solution is a pair of wire cutters... until the state makes it illegal to tamper with these, like it is with odometers.
Ah, what the hell... I've the karma to burn.
This level of rampant paranoia cracks me up. To hell with the positive benefits of making cars safer in the long run... no, let's strap on our tinfoil hats and find the black lining. Watch out, michael! Casio has made a deal with the porno industry! They've put a chip in your wristwatch so they can measure your pulse rate and report back on what particular twisted fetishes get you off the most! Watch out! Booga booga booga!

I dont know about any of the other implications of this device but I would be extatic to replace the whole, 5-to-10-miles-over-is-sortof-accepted-by-the-cops- so-long-as-their-in-a-good-mood look at speed limits. If speeds cars were monitored every minute that you were driving the assholes that think they can handle their car going 90 down the turnpike would either stop or be arrested. and the rest of us could travel safely at 70-75 without worrying about getting a ticket for going 4 miles over teh speed limit.

Man... I don't know if this is what I want America to become.
Are the police gonna tap into this? Wirelessly be able to find speeders? Everything's becoming so technical. "Well, the hot coffee was TOO hot, I want $200 million." "Well, my parents were segregated by racist whites... but I still call that this kid I see sometimes a 'white boy' or a 'cracker.' But I'm just kiddin' around, I'm sure it doesn't really bother him."
I guess I'm just ranting about the details of society in general.
But I really believe at some time we're going to have to ask outselves... how far is TOO far in what we do, and can we ever just let certain things go, even if it does giving up some profits?
Nahhhhh...
The next comment I write will be ready soon, but subscribers can beat the rush and see it early!
Are the blockboxes on airplanes to infringe upon the pilot's rights? Of course not, they're to analyze in the case of an accident, to help understand the problem, and improve safety for all. There are many undoubtedly many, many, many car accidents that could be prevented, by better crash analysis.
If folks are so paranoid about being recorded, they should go live in a cabin on a mountaintop. Keeping a record of goings on is an aspect of society which is a good thing, and more of it is better, providing more safety and security. If you don't like it, go join another society. If you're *really* got that much to hide, the cabin on the mountaintop is probably best.
Anybody who does use any such data for other uses will be "outed" so quick it will make your head spin; look at the rent-a-car fiasco.
Love many, trust a few, do harm to none.
Buy car. Buy Taser. Unplug unit. Apply 120,000 volts. Plug unit back in. Drive in privacy. (Ignore warning light optional.)
Of course, if you hack it, even better.
Personally, I'll stick to upgraded older cars. I prefer 5-points to airbags anyway.
get ready to have your insurance company jack your rates for going over 65mph
The article didn't mention anything about information gathering for non-crash puposes, that I saw.
Anyhow, if insurance rates do go up for speeders, they should correspondingly go down for those who abide the speed limit. Wouldn't that be the kind of rewards system we'd want to build into the process?
Why are you letting these clowns ruin our country?
I doubt that they'll settle just for hiking your rates for driving too fast.
Heck, they might even go as far as to limit their liability if black box indicates that you were driving too fast at the time of accident - or prior to it. Or deny further coverage based on this etc..
Imagine sensors tracking your head or the usage of radio buttons or wether you used the turn signal. What about that stop sign before the intersection..
Yes it sounds like insurance company's heaven and a regular driver's nightmare.. Especially if it goes to that failure to follow traffic regulations limits insurance companies liability.
Around here if you're only doing 65 you're likely to get ticketed for impeding traffic.
Well, not quite, but the legal limit is 75 on the interstates here (Colorado) outside the city. And there was some discussion about getting tough with drivers who drive under the limit in the left lane.

I heard about this about 6 months ago being experimented with in Europe. It's a wonderful idea, especially in New Jersey which has the highest car insurance rate of probably anywhere.
The way it worked in this test program was a small monitor would gauge your speed (now that I think about it, another monitor guaging breaking habits could also be useful) such that if you were obeying the speed limits, you would get a discount on your insurance.
Insurance companies want to base rates on potential of accidents, and therefore, currently use statistics to determine rates. This means that I have an extrordinarily high insurance rate even though I'm a good driver simply because of my age and gender.
The idea isn't to fine people automatically (like in Demolition Man) but to reward people for good driving habits. The real piece of technology that needed improvement was GPS -> speed limit mapping, once that is perfected, I personally can't wait to sign up for this type of program.
int func(int a);
func((b += 3, b));
These boxes are in fact orange!
Its just not a standard yet.
Impeding traffic in ANY lane should be ticketed just as heavily as speeding should. Think about it, if I am going 65 in a 55 and you are in front of me, I am coming up on you at 10mph faster. If I am going 55 in a 55 and you are in front of me going 45, I am STILL coming up on you 10mph faster. The situation is just as dangerous.
More dangerous if you want to get picky because there is a slightly smaller percentage difference between 55 and 65 than there is between 55 and 45.
I just wish the cops would realize this and either leave the speeders along or pick on the idiots running 40 in a 55!
This idea of putting something similar to black boxes in cars is nothing new. CART has started putting crash analyzers in cars. CART has been doing it for a couple of years (They call them "Blue Boxes" because they're made of blue aluminum and are from Ford), and NASCAR has been talking about them since the accident with Dale Earnhardt. They use it to make our passenger cars safer. If this does come to the consumer market, I can assume that this is the only reason it would be used for. The only thing I can see that would screw this up is the amount of time it takes to analyze the data. If they can make the time it takes really fast, then it could be used to put the blame on accidents and disperse tickets accordingly.
No TiVo and no caffeine make me something something...
Just what we need: one more piece of crap to add cost, weight, and take up space. Benefits for insurers, law enforcement, just about everyone except the poor fool who has to pay for it.
The information might be useful for analyzing the survivability of some crashes and using that information in later design, but as far as establishing cause or liability, it is less useful.
Oh sure, the speed and braking info helps some, but without some sort of record of the external environment, you don't get the whole picture. Consider a collision resulting from somebody running a red light -- with no reliable third party witnesses. Data would likely show both vehicles at normal speed -- which driver didn't see the light?
Or a multi-car pileup in sudden white-out conditions -- which happened to me on an otherwise clear, sunny day when a sudden gust of wind blew snow from a field beside the road across the highway, reducing visibility instantly to zero (and unfortunately, somebody decided to slow down at a rate faster than those behind him). By the time the cops showed up, it was a clear, sunny day again.
Or driving at or below the legal limit, but "too fast for conditions" (fog, slick roads, etc) where the conditions are transient (as the above scenario).
Why not just mandate installing video cameras looking over the driver's shoulder?
-- Alastair
This was done secretly a while back by the NTSB. While studying the data they noticed something intersting. In almost all states an average of 86.7% of the driver's last words before an accident were "OH SHIT". The only exception was Tennessee where in 63.2% of the accidents the last words were "Hey Bubba, watch this" ;)
Sorry, couldn't resist.
The only athletic sport I ever mastered was backgammon - Douglas William Jerrold
No argument from me about that.
Actually if I recall correctly, there was actually a proposal to have the cops ticket people going the speed limit in the left lane if the flow of traffic overall was at a higher (and technically illegal) speed. That suggestion was shot down, but did get some popular support.
-- Alastair
Hey, I've found a neat way to avoid getting speeding tickets. Here's how it works. It turns out that on almost any public road there will occassionally be little white signs on the side that have a number on them. There's also this little indicator behind the steering wheel that has its own number that goes up or down depending on how hard you push the gas pedal.
Now here's the trick: If you make sure the number on this "speedometer" doesn't exceed the numbers on these "speed limit" signs, you can cruise right on past the cops and they don't even seem to notice you! Just leave a few minutes earlier and you can get to where you're going on time without anybody stopping you to harass you about your velocity. Works like a charm!
Psst, don't tell too many people. The cops might start to catch on that we've found a way to avoid them. Heh, those suckers.

I admit it. I speed every day. Yes, that's *every* single day that I use the roads. 99% of other road users do exactly the same and you know what?
The roads are safer than houses. In the UK, you have more chance of being killed by an accident in your home than you have on the roads. Don't believe me? 4000 people killed in accidents in the home in 2000 and 3,500 killed on the roads.
Speeding is only targeted because speed is easy to measure. That's it. It's a cop out. The fastest roads (the motorways) are also by far the safest roads.
The vast majority of accidents occur in urban roads with a 30 limit at a junction and *don't* involve speeding. They are caused by lack of observation. "Sorry Mate I Didn't See You".
Putting black boxes into vehicles isn't in any way going to improve driver observation.
What just might improve road safety? Compulsory driving tests after an accident or compulsory advanced motorist training might just make a difference.

Personally, I would be more in favor of a standardized system that would allow Police to pull data off a wrecked car to find out more about the crash. Since, as other people have mentioned, it would be hard put to use such a device to determine LIABILITY, Police (and Insurance) will still need to be satisfied with witness testimony. Being required to actively "pull" data from such a system, the potential for abuse will be greatly diminished.

Here they'll give any nimrod who walks in the door a license. I used to live down in Florida and they always had horror stories like the one about the 86 year old lady who was legally blind and failed her driving test 26 times before finally managing to do well enough to get a license. You can't go flying down I95 at 90mph because someone like that will cut you off doing 45mph. Of course, that doesn't stop people from flying down I95 at 90mph...
There are sections of interstate near my house where the average speed of traffic is 90-100 mph and those speeds are not intimidating as long as you've got a mile or so of visibility to see what traffic's doing ahead of you. Most of the drivers on the road here don't pay enough attention to be able to maintain such speeds safely. I don't think the ever-popular SUV will ever be safe at those speeds. Especially with the driver yacking on a cell phone.
It would be easily possible to actually monitor and ticket every car on the road going over the speed limit but if that happened here in the states, the speed limits would be quickly raised or eliminated on the highways, since it'd piss off literally every driver in the country, and almost all those drivers are eligable to vote. Selective enforcement, while technically illegal, works fine for keeping most drivers to within 10-20 mph over the posted speed limits.
The arbitrary nature of the speed limits are a pain in the ass though. I've been dinged for going 20 over the speed limit at 2 in the morning with no other cars on the road. And you can't argue that, even though road conditions were perfect for it. And I've seen people doing the posted speed limit in conditions where that was extremely dangerous. I'd like to see road conditions play more of a part, but I guess you can't trust many of the drivers on the road here to be able to judge them correctly.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
But I digress....
As part of the test, Progressive also patented the algorithms to turn such black box data into insurance rates. Prog isn't the type of company that would license that tech (I am a pricing actuary at a competitor.
A little gossip from some folks I talked to a Progressive, BTW: Although the GPS data was predictive enough to let them consider doing away with other seemingly intrusive underwriting analysis, the thing that was really predictive was the whether a person was willing to let a black box be installed in their vehicles. All other things being equal, people who were willing to be monitored had fewer accidents than people who weren't.
I seem to recall a story about two guys who drove down the Don Valley Parkway (4 lane highway connecting Downtown Toronto to the suburbs) side-by-side at the speed limit (90km/h). They were ticketed for obstructing traffic. I guess you just can't win.

Well, according to your black box, your lights were on, and you had come to a complete stop.

Remember "Bring 'em on"? *sigh
Putting a lot of expensive high-tech electronics into cars to collect crash data is stupid. First, you pay for a lot of gadgetry. Then, insurance companies will have a field day holding people responsible and refusing to pay out.
Come to think of it, there's an easy solution to all this: DON'T drive with cash and baggies of heroin in a nice pile on the passenger seat. Don't drive with a dead body in the trunk. And don't drive like a maniac at 2am on a Saturday morning. Or any other time for that matter. I mean, it's dangerous.
That said, I'm not happy with the notion that black box data could be arbitrarily retrieved regardless of whether an accident has occurred. Such a box could be used to track where anyone in the country has travelled, and that strikes me as being a first step towards illicit monitoring and even travel controls.
It would be a shame if the very real threats to civil liberties that a badly implemented black box system would create were obscured by people whining that their inability to drive safely might be discovered.
You are not alone. This is not normal. None of this is normal.
I'm not really sure it's so paranoid to be concerned...
Here's a scenario that is really off the way and probably totally unlikely, I present it just to stoke the fire of paranoia even further.
Your car gets stolen because you were stupid and left your keys inside. The thief then proceeds to read the data from your black box, noting all the places you stopped... then goes to each place and ransacks what he can using your own keys to get in without trouble.
Think of the fuss that would be raised if they made a movie showing some spy downloading data from the exisitng OnStar system in a car to determine where a secret hideout was!
"There is more worth loving than we have strength to love." - Brian Jay Stanley
Oh, come on. On any given day, there are far more people in homes than on the roads (since not every can or has to drive, but everyone lives somewhere). And on any given day, the typical person spends far more time in his/her home than in his/her car. Yet the difference in numbers is only 500? Why are the cars so fratzen dangerous, is what I want to know.
I recognize the privacy issues and goodness knows, they should be addressed. But isn't it time for us to recognize that the only part of the driving system that has not improved in a century is the driver? Why the heck don't we have cars driving themselves and using state-of-the-art sensors -- many markedly superior to eyes and ears -- to avoid danger?
The Mongrel Dogs Who Teach
The situation might be as dangerous but they are not equivalent. In the first, you are breaking the law as you approach someone obeying it. Why should that person be held responsible for your breaking the law? If "impeding traffic" were enough by itself, then that allows the most aggressive idiot -- the guy who needs to go 90 mph in a school zone -- to set the limit for everyone else, since eventually he'll overtake (= be impeded by) anyone going slower.
Now, the guy doing 45 on a 55 road is also causing trouble, even for the people going the speed limit. Which points out that "speed limit" is a dumb concept. There should be a "speed range" (50 to 60 mph, for example).
The Mongrel Dogs Who Teach
So far all the comments that are +3 or higher are either, "The cops are just gonna use this to hand out tickets to me. Quick narc'ing my rights!"
Blah. Okay, assuming for a minute that these devices even would be used by the police to monitor speeding and hand out tickets (that hasn't been stated, an in fact has been ruled against in CT already), IF YOU'RE SPEEDING AND YOU GET A TICKET, TOO BAD!!
Here's a little-remembered fact: speed limit (emphasis mine) means the maximum speed at which one can drive. Now you may whine and gripe six ways to Sunday if you get pulled over for doing 32 in a 30, but guess what? You broke the law. It's a black-and-white issue to the courts. You can come up with 10,000 reasons why you're a good driver, the speed you were travelling at was safe, ad infinitum typical American tomfoolery, but the fact is that you BROKE THE LAW.
I can't stand the speed limits in certain areas either (by the way, I'm an American) but whining about it doesn't do a thing except make you look pedantic. Grow up. IF this technology is used to monitor driving, and that's a big IF, then it might actually force you to follow the law. What a concept.
And yes, I know in Germany or Switzerland or Cochabamba or whatever they have higher speed limits, fewer fatalities, etc. Newsflash: this isn't Germany.
Now, back to the original point, consider the "crazy" idea that maybe, just maybe this idea was started by decent people who aren't a Gestapo and have a legitamate interest in improving vehicle safety. My, what a silly idea!
I didn't mean to imply that the guy going 55 in a 55 should get in trouble because I am going 65. Merely that the guy going 45 in a 55 should get in just as much trouble as a guy going 65. Both of them are 10mph off the speed limit. As such both of them are putting the other drivers in a situation that is going to cause one driver to come up on another driver at 10mph faster.
The FAA expressely prohibits "Black box" (CVR/FDR) data from being used in any legal enforcement action. It is only accessible for accident investigation and safety purposes. In other words, an airline can't legally snoop the data and decide to fire you the pilot just because you did something wrong. Only if there was an accident, and the NTSB, using that data after the fact, proves your fault, then only in that case, the data plays a role in any discipline action.
One can only imagine that they will make such a policy for cars, hopefully!
There's 10 types of people in this world, those who understand binary and those who don't.
I have to disagree with you, I feel impeding traffic in the RIGHT lane (or the slow lane in regions where slow != right) should in general be acceptable.
This should be the case for a few reasons: for saftey reasons, certain classes of vehicles (big trucks) have lower speed limits than others (passenger vehicles), so they have to impede traffic in order to drive safely (i don't know about you, but i don't want big rigs driving 90 mph); mechanical issues can sometimes limit speed to some maximum, that is within reasonable speeds for a road, but may not be what others are driving at, so the driver should move to the right lane, and depending on their destination, and severity of the mechanical issues may need to stay in the right lane for a while.
I do think that in addition to maximum speed limits, minimum speed limits need to be posted, and enforced, and certainly slower traffic should stay to the right, unless theres a reason (such as an offramp) for them to be on the left.

I am a bit of a car nut, and I know of a couple of cases where telemetry data has been used against car owners:
On the 1995 M3, BMW noticed all sorts of warranty claims coming in about blown motors (like the first 2 cars in the country, within a week of delivery). They eventually traced the problem to people missing shifts, going from 4th to 3rd as an example, under heavy accelleration (that IS why you bought an M3 after all). The very smooth gearbox (I can shift into 1st in my M3 at 80mph without a problem) combined with soft transmission mounts meant that missing a shift was VERY easy, in some cases, there is NO WAY to tell you put the selector in the wrong slot.
In 1996, BMW switched their cars from Bosch to Siemens electronics, and put a telltale feature on the motor management system. If the car went over the redline, it would set a fault with the RPM saved in memory. A few M3 owners have sued their BMW delaers with claims that they didn't over rev the engine but dealers denied warranty coverage and a few of those cases have been true. One way to tell if a dealer is trying to stick you is to look for a printout of the RPM fault, if the number is not divisible by 256, they are making it up.
Another example was the case of a hit and run driver in a Caddy SUV (the Navigator monstrosity I think). The police responded to OnStar's call, the system on the Navigator having called in after the airbag was deployed. Of course, with GPS, it gave OnStar gave the cops the exact location of the accident (but not updated information of where the driver had gone). The cops followed the nice trail of coolent and parts to the Navigator driver's home and arrested him...

Roughly 50% of the accidents I work are Motor Vehicle Collisions. NOT Motor Vehicle Accidents - no such thing exists. Speed is the determining factor in the severity of the accident both to the person responsible for the collision and the innocent people they hit. If everyone followed the driving code to the letter of the law, collisions would not occur - and anything that helps my cop friends (I see them at every accident) better determine what each idiot was doing is a great idea. Also, consider the prevention capabilities - the black box sends a warning to the cops that such and such a car is weaving and speeding on such and such a road, and bam - they pull his drunken ass over before he kills someone.
Ever yelled at someone who went through a red light or thru an intersection without stopping? Ever yelled at that asshole in front of you to get off of his cell phone?
I relish the privacy of my home. Driving on public streets, however, is in no way a private act. Each and every one of us in a car is weilding 3000 lbs (minimum) of momentum (speed dependent). That carries with it a significant amount of responsibility, which in turn carries a requisite amount of accountability. These black boxes would enforce that accountability. How is that a bad thing?
It will surely monitor your driving habits and give the insurance companies more reasons to refuse to pay. It'll allow cops to trace you but won't help in pinpointing your position if you have an accident.
If you were speeding and you had a collision, why should the insurance company pay? If you and I have policies with the same insurance company, it's my monthly payment that goes towards the money you get. Is that in any way fair? I follow the law, you break it, and you get my insurance money?
It's not that I don't have my tinfoil hat, it something called *REALITY*. Try it some time - it'll change the way you see the world
The stats include motorcyclists, cyclists and especially, *pedestrians*.

I didn't say the technology wouldn't be necessarily be implemented. Simply that it wouldn't last.

You can hypothesise about it all you like. The reason the insurance companies offer something like this is probably be because there's a statistical link between not speeding and having a lower rate of accidents.
If there wasn't, they wouldn't offer the discount.
I can agree with that, schoolbuses are limited to about 45mph, and despite being very annoying that is to insure the safety of our children. Mack trucks however are often the fastest things on the road! I'm not saying I'm comfortable with that, just that those guys seem like the worst speed limit breakers.
I think it should probably go by what is the safest operating speed. I school bus going 55 in a 55 should be brought under suspicion. I mack truck going 85 in a 75 should be more harshly punished than a car doing the same. Some would call this unfair, but a commercial drivers license should bring with it more responsibility, as should being allowed to drive such a large, potentially destructive vehicle.
Blackboxes, maybe even with 802.11 so the CHP can spy on you (drives fast, changes lanes frequently, tailgates, yeah... better send them a recruitment letter), beyone the obvious invasion of privacy argument (He's parked in front of your house again, sarge, shows up two minutes after you leave for work everyday...) there's certainly going to be a firestorm of protest at jacking up the cost of cars. We'll spend insane amounts of money once we got them, but don't even think about charging $200 more on the sticker price...
A feeling of having made the same mistake before: Deja Foobar
There are times it is acceptable to exceed the speed limit: passing, before going up a hill, etc. Also, a speed limiter that worked in Hawaii (55 mph limit) might not work too well in Montana (limit = what the police think is safe for the roads and conditions). A speed limiter would have to be an extremely complex piece of technology to tell whether you were going 70 mph down a residential side street or passing someone at 70 mph on the interstate. Not only that, but it can also be unsafe to go slower than the speed of the traffic around you. If you can't go faster than 70 mph, but the traffic around you is doing 80, then all those non speed limited cars may end up crashing into you because they expect you're going faster. There is no really safe and effective speed limitation technology available.
That's it. I'm no longer part of Team Sanity.
Actually, the days of the Richtgeschwindigkeit (i.e. that voluntary speed limit on German Autobahns) are long numbered. Nowadays most Autobahn stretches have posted compulsory speed limits, just like everywhere else...
Say no to software patents.
As a registered Tennessean, I object to those kinds of stereotypes!
If you must know, approximate last 30 seconds of any Tennesean auto accident are:
"No kiddin! I am driving and talking on one of them new fangled Walkie-Talkie phones! Oh, crap! I dropped it! (SHOUTING) Stay on the line bubba, I'm gon get it!"
Oh. That's a pretty reasonable thing, then. That's why speed limits should be speed ranges.

That my friend is the truth the world over...
We have horrible accidents in the US with DUI and truckers falling asleep too.
Good luck to you.
Newer model sports cars log the highest RPM and/or speed that they've hit in order to protect against overrev damage warranty claims to the valves, etc, as a result of mis-shifts to racing abuse. It is likely possible to get the codes cleared with a scan tool, but if they're non standard, there's no standard tool for doing it. The Acura Integra Type-R has been rumored to have the ability to tell if the owner has put the vehicle past redline.
This isn't to say you can't fool the ECU. Boxes exist now that take the vehicle speed sensor (VSS) input to the ECU and report a lower value than is actually being travelled to get around speed governors which are mandated by law in Japan and put in on some cars (most SUVs will not go faster than 160 km/h). This isn't to say you can't just replace the engine computer altogether, there are many products that do this already from manufactuers like Haltech, AEM, Motec, etc.
This gadget is too easy to work around, and there's no incentive for consumers to put it in their cars if they don't want to. It is a myth that high speed has anything to do with safety - it's usually the slow drivers with bad situational awareness the cause accidents.
What it is, however, is one more step towards mandated government control of vehicles, and is bad news. Changing the ECU is illegal now, because you're tampering with emissions equipment, so messing with one of these gadgets would be, too.
If legislators really gave two shits about safety on the highway, they'd make professional driver training manditory - think a few hundred hours of training, not a weekend - and reinforce that with 5 year re-evaluations of drivers. I've chosen to spend lots of money taking performance driving schools and learning how to drive, something which has saved my ass from an expensive accident more than once. A stupid little black box is not going to help the soccer mom with no idea how to merge into a 120km/h highway traffic flow, or how to do simple brake and avoid maneuvers in a top-heavy vehicle.
..don't panic
Tell that to Disney. Or do you mean that they can only buy them?
Yes, they can only buy them. Thanks for eloquently, if circuitously, demonstrating why blind trust in government is a bad idea. That corporations would want to influence lawmaking is only a problem and only remotely relevant because our legal system allows them to do so. Fix the legal system and Mickey's no longer a problem.
In most cases I would agree with you, but the DVP does some weird curvy things once you get south of Don Mills Road, all the way into downtown. If you don't know the curves, you could easily end up upside-down in the river valley before you know what happened.
Reality has a liberal bias
the autobahn does have a speed limit of 250 km/h. it is enforced in an odd way though: car manufacturers must speed limit their cars to 250 km/h.
i also notice that german drivers are far more skilled than US drivers. i've been surprised many a time to find drivers in germany (contrary to my low expectations) observant, forward thinking, and skillfully agressive, yet they know when to be careful (pedestrians and bicyclists are treated like gods). and i've noticed a higher percentage of people brake before turns, and accelerate through turns, then i've ever seen in the US. i'm sure many an accident on 17 crossing to Santa Cruz could be avoided if people actually slowed before entering the turns in rainy weather, rather than nailing the brakes at the apex.
Each and every one of us in a car is weilding 3000 lbs (minimum) of momentum (speed dependent).

I put "speed dependent" there for a reason - momentum is p = m*v where m is mass and v is velocity.
Pounds (lbs) are a unit [wihatools.com] of force or of mass.

Using Newton's Law F = M*a we see that mass and force are related by acceleration; therefore pounds can be both force and mass if and only if the acceleration is zero, which is not a very interesting case.
For momentum, you'd use lb*ft/sec
And you'd be wrong. the English unit of mass is the slug, which is equal to 14.6 kilograms. The pound is in fact a unit of force, equal to 4.45 Newtons. Therefore the relation "momentum = lb*ft/sec" is wrong; the correct relation is
momentum = lbs*sec or m = F*s. You can derive this using p=mv , F=Ma, and a=m/s^2. I derived it myself, and I didn't need a website to do it
(Yes, this is non-intuitive. If you still do not believe it is correct, however, consider this: 1) the English equivalent of the Newton is the pound; 2) the SI unit for momentum is either one of kg*m/s or Newton-seconds. Therefore the English equilavent of Newton-seconds is pound-seconds = 4.45*Newton-seconds. As a side note, this sort of unitary tomfoolery is typical of why Britain, an empire which once spanned the globe, is now an island
