Is Your GPS Naive?
mi writes "Many GPS devices today will try to scan the FM bands for traffic advisories in the area to display on their screens. The signals, however, are neither authenticated nor encrypted, and one can — with commonly available electronics — construct a device to broadcast bogus advisories. Possible codes range from "bullfight ahead" to "terrorist attack"..."
"Speed trap ahead."
I too have felt the cold finger of injustice.
Why would you have a "terrorist attack" code for a traffic warning system? Okay, so I can see how maybe they might close off streets for emergency personnel, but couldn't you just leave the code at that - "Roads Closed"? I mean, if you go telling drivers that there's a terrorist attack ahead of you, they're going to panic, freak out, and maybe get into a car wreck.

the writer seems to think encryption can solve this problem, encryption cant help here as the system is unable to communicate back to negotiate the setup, and if the signals are encrypted with a predetermined key it will be susceptible to replay attacks... how different is this to a common radio channel telling its listeners that there's been a terrorist attack etc? the issue seems to be more of a hype than a real concern...
Or alternatively, you could just drive the speed limit.
I never said 100mph was safe or reasonable... but there are many, many places where the road can (and does, every day) handle traffic safely at 70-75 instead of the posted 55, or 45-50 instead of a posted 35 (excluding residential areas). Many of these restrictions are due to arbitrary laws that say, in essence, "speed limits must be X within Y miles of a city", with no regard to the actual road or what it could safely handle.
Look up the video sometime of when a bunch of college students lined up across I-285 in Atlanta and did the posted speed limit (55). Traffic backed up for MILES behind them.
A much bigger threat than pure speed is people who don't pay attention, and realize "Oh crap, that's my exit, four lanes away!" and proceed to cut across said four lanes. Or those who don't bother to check their blind spots when changing lanes, or don't realize that their lane is ending, or don't signal... or insist on driving slow in the left lanes.
And again... if the purpose of limits really was to promote safety, cops wouldn't have to hide. And there would be no penalty for warning others of a speed trap, either. They don't arrest you for saying to someone, "don't rob a bank, the police will get you!" so why should saying "don't drive fast, you'll get a ticket" be any different? Oh, wait, then the local government won't get its traffic fine revenue... and God forbid that the residents pay for their government themselves...
The meek may inherit the earth, but the strong shall take the stars.
Of course you realize that you, too, are breaking the law. Yielding to faster-moving traffic in the leftmost lane is required by law in most states -- it makes no difference whether you think the other person is going "too fast", you're still causing a safety hazard, and I know several cops who love to give out tickets to people who are causing unnecessary hazards like that.
The speed of safe travel is not an absolute thing, when you're dealing with groups of people the safest speed to be traveling is "however fast everyone else is going", even if it is in excess of the posted limit, and traffic laws do generally reflect that.

In too many localities police will usually let a local resident off with a warning while ripping others off. This keeps local residents (who attend council meetings) content, and brings easy revenue (people from afar are very unlikely to challenge the tickets in local court) to the town. This selective enforcement gets documented occasionally and is a real bane of highway travel.
NJ's Governor Corzine just had a nasty accident, because his driver (a State trooper, no less) was going 91 in a 65 mph zone (Governor's vehicle can only do that in an "emergency"). The governor will take months to recover, because the moron was not wearing his seatbelt. Neither the hypocrite trooper (who had a similar accident a few years ago), nor the hypocrite governor are expected to be punished by law, although tens of thousands drivers are fined in NJ for the same (and lesser) offenses every year — most of them without causing an accident.
The speed laws are not reasonable — they take neither car's age and quality nor the driver's experience and health into consideration. What's too fast for an inexperienced 17- or half-blind 70-year-old driving a Buick is unreasonably slow for a healthy middle-aged driver driving a BMW...
In Soviet Washington the swamp drains you.
They said you do not have any obligation to move or go faster than the speed-limit whatsoever.
Your primary obligation is to drive safely and avoid accidents. In most cases, that means that you don't have to go faster than the speed limit, but you still have to heed "slow traffic keep right".
Honestly, I think your type are assholes.
I stay with traffic flow, and I haven't gotten a moving violation in the 20 years I have had a license. And if you drive too slow in the left lane, I keep a safe distance.
Nevertheless, I have my opinion about people like you, and let me say: you're the asshole. It's people like you who put some intellectual game ahead of the safety of people around them. You know full well that you will get some bumper-hugging type-A personality behind you who doesn't keep safe distance from you, and when you two have an accident on the highway, you're going to take other people with you and block traffic for hours. You're just as much a "type-A" personality as the person who speeds, and you're just as dangerous. It's just that you're passive-aggressive instead of simply aggressive.
The only safe thing to do is that if the guy behind you isn't keeping a safe distance, you get out of the way. If you don't, you endanger yourself and everybody around you needlessly.
So in 2 of your 4 accidents, you were driving too fast, and were unable to stop when something bad happened in front of you. Hence, you rear-ended someone. Presumably the insurance company held you to be at fault. You might have been driving at low speed in absolute terms, but you were clearly driving too fast--or leaving inadequate stopping distance, if you want to look at it that way.
