If you can't get out of a situation with 30 seconds of full throttle, you should never have gotten into it. Perhaps you should think of the oft-unused brake instead. Brakes can make much higher velocity changes (saving your ass in situations like you describe) than the accelerator can.
Anyway , you could set it so that it disengages only at maximum throttle and for 30 seconds. If you *really* need to *really* go faster, then it's much more natural in an emergency situation to fully floor it then press a button. Yes, that will mean that some idiots will drive at full throttle, but also allows it to be overridden in the most natural way (as opposed to a button you have to press).
30 seconds of full throttle is a *long* time and a lot of distance too... probably at least two or three miles (starting from 60mph) , for most new cars.
And it's annoyingly hard to 'casually' speed when all you've got is full throttle / no throttle.
There's normally a detent / button to press or something for this reason, otherwise it's easy to rotate the ignition switch all the way round to off, turn a little bit, hear a 'click' , think "oh, shit!" and then have your car gently curve towards some large immovable object while you frantically jiggle the steering wheel and ignition key to unlock it:-)
I've an article on the mercedes system at home somewhere - they have a large degree of redundancy, as all of these kinds of systems should.
From memory: Two thottle position sensors, wired opposite (one reads high at full throttle, one reads low at full throttle)
Same goes for the accelerator pedal sensor.
The throttle body still has a rather robust spring on it, and there's some sort of electromagnetic clutch to disengage the drive unit from the throttle body if computer position != wanted position , which *should* cause it to snap closed if something goes wrong there.
The computer still has injection, ignition, boost (in some cars) and idle control, so even at a jammed-wide open position, there's still a reasonable amount of control with ignition/ boost / fuel limiting. But your car does run like a goat though.
And there's enough leeway in the idle speed control system for a 'limp home' mode (at 25kph).

Welcome to the mysterious future,grampa;-) Ah, the Simpsons. Is there any topic they *haven't* touched upon?
Fluoro's do go dimmer after a while , and it's quite subtle. Until you actually see the difference between an old lamp and a new one side by side, that is.
There's probably a design code for your building that goes "workers must have 'x' many lumens of light available if doing desk work". When the fluoro's get dim enough to go below the limit they get changed out.
Or, maybe they *are* just trying to save a buck or two and do a whole batch at once;-)
It's probably the phones RF output device getting hot.
As the RF stage is the main device consuming power in your phone, and it's not 100% efficient , a certain amount of energy will be dissipated as heat.
(blockquoted from a site discussing avgas refuelling):
Shell have issued a warning about mobile phones - they have reported 3 incidents recently where mobile phones have ignited fumes whilst being answered/ringing during fuel operations:
1. A phone was placed on the boot lid during refuelling, it rang and the ensuing fire destroyed the car and the pump.
2. An individual suffered burns to the face when fumes ignited as he answered a call during fuelling.
3. An individual suffered burns to the thigh and groin as fumes ignited when the phone, which was in his pocket, rang during fuelling.
Why did it happen?
It is a misconception that Mobile Phones can't ignite fuel/flames. It is believed that the more modern phones (those that light up when either switched on or when they ring) have enough energy released to provide the spark for ignition.
Learning Points
1. Mobile phones should not be used in filling stations
2. Mobile phones should be turned off before exiting the vehicle when stopping in a filling station.
Check the relay domains in the message headers. If they don't match the 'From:' domain, don't bother with the autoresponder.
That way a from of "foo@foo.com" and a relay header of "mailserver.bar.com" is pretty likely a spoofed address.
Caveat: I've not recieved the new variant of the SoBig virus yet, so I can't tell about the headers.
The procmail scanner / html sanitiser I have installed from impsec.org does this automatically (and weeds out a lot of that obnoxious html crap as well).
- Run over by 290 ton dump trucks. Phone? What phone?
- Dropped into various parts of an operating washplant (all ending with at least a 12 inch inlet impellor pump running at 2000RPM waiting for the phone)
- Dropped down 70 meter boreholes and then subsequently blasted to bits when said boreholes are charged with explosive and fired. (From memory in this case, they dropped about a cubic metre of dirt back down the hole to seperate phone from explosive before charging the hole.)
A good thing about typewriters is that they force you to *compose* a sentence before typing it.
I'm sure that if there was some typewriter-based version of the internet (eg, no backspace or delete - the horror!), there'd be a lot less flamewars and random crap on it, and a lot more real thought involved.
Or maybe we'd just get a whole lot more spelling mistakes - lord knows, I've hit the backspace key about 15 times typing this up;-)
Russian Guy: So, if you just sign here.... and here... and (flips page) here... you'll be the proud owner of a 1963 model FissionMatic Nuclear power plant! Oh, we haven't put in anything for shipping - we'll leave that up to you.
Korean Guy: Excellent! (signs)
Russian Guy: Ok - that's all done then. You can pick it up from our factory near Olympus Mons anytime you like. (flees building)
Problem is , if it's a main distribution board, there's no way to safely uplug it unless you're an electrician.
If it's as much a rat's nest as he says, there could be anything in there, such as neutral or earth leakage currents that'll still give you a hell of a jolt.
In cases such as this it's strictly No Touchy - get an electrician. End of story.
Right now he's screwed. If something *does* go horribly wrong (building burns down, or someone gets zapped) *HE* was the last person to have been in that board. People looking for someone to sue now have a lovely target, if only for negligence. He needs to get a qualified person in there RIGHT NOW.
A friend of mine and I were leaning over a running engine on opposite sides of the car. He touched an ignition cable and the current went: - Up his arm - Down his legs to earth - Up *my* legs to crotch - from my crotch to frame of car that I was leaning against to look in engine bay.
Oh , I don't know about the maintenance - if you don't maintain a superconducting fuse widget (eg keep it cold.... er what else is there?) , I suspect that it'd stop working pretty quickly.
This is opposed to 'normal' protection devices that fail to actuate when broken, a superconducting thingo would actuate when broken.
(Notice my use of the technical terms 'widget' and 'thingo', and bow down to my enormous knowledge on the subject;-)
Btw.. i still cant understand the logic behind the reasoning that some countries have an inherent right to keep nuclear weapons, while the rest should live without them. Why dont we all give it up???
It's flawed logic - eg. Bush:"OMG! Iraq has weapons of Mass Destruction! They can't have them! Invade!"
Passer-by:"Er, doesn't the USA have a whole lot more WMD about the place? Pot - kettle - black?"
Bush:"But we're more *responsible*."
Passer-by:"Er, but you just flattened that country with your military might - so, you have used a weapon of mass destruction there... your military. Admittedly, I didn't agree with their method of leadership but still, you've pretty much overrun the place. And we haven't seen much of any WMD's whilst you've been occupying it."
It was, however, the equivalent of losing power to a few square blocks of Manhattan or downtown Chicago.
Yeah, for *five weeks*. Not good. If you lived or worked there, and was told you couldn't use the power there for 5 weeks, you'd be pretty pissed off. This was the central business district remember, and Auckland is a large city by NZ standards. Find the ratio of 74,000 people powerless to the total Auckland population and apply to Manhattan and see how it'd go.
Anyway it was one big fuckup, that's for sure.

But it's a fact that everyone has a distorted view of people in other places, simply because they don't live there - the only things they *do* see are the extremes, because the norms slip underneath the radar and go unnoticed.
And if you're Australian , and I'm Australian, I'm pretty sure that Australia is not a hoax, but I'll agree with you on the Fosters remark:-)
And the LAN browser is better in my opinion (direct links to shared folders are faster)
Unless you're on a network with a lot of shared folders. Lotsa clutter there - I prefer the computer -> shared folder hierachy better for this reason.
Also XP has the annoying problem of wanting to check every single shared folder listed there when you open "My Network Places".... oops , no good if you VPN to a few different work subnets and collect a few shared folders off each subnet. Suddenly "My Network Places" refuses to open. Great advance there guys!
If anyone knows the off switch to this "feature" tell me.
What about patch 811493? No blue screen, but a pain-in-the-ass slowdown and crap system performance. That was in April.
Four months - that's "been like ages"?

Or perhaps a accelerometer input on an axle to register potholes. Actually , a pretty good gauge of road surface (gravel size etc) could be sensed with a decent accelerometer, as long as your tyres are fairly well pumped up.
(Car hits pothole - ka-THUNK!!!!)
Computer : Crikey! Didja feel that!?! Stone the flamin' crows, who was the bushwhacker that built this goat-track? Strewth!!
(Computer makes note of position for future reference.)
That way, subtle potholes (eg small depressions in road with no sharp edges) could be picked up fairly well.
And I hold the patent for "a method for use of Australian Slang to accurately measure and describe road defects", so no getting any ideas;-)
That may be, but I have yet to hear a single person say, "Their conclusions are not what I believe to be true yet the study was flawless."
That's because most people when confronted with the findings in such a manner believe them.
If the study is flawless and reaches some conclusion, then scientifically-minded people will accept the results (or at the very least, go and duplicate the study). Not accepting the results implies that you don't follow the scientific method.

for example, tires on a car probably wont be pressurized more than 40 bar

40 bar? holy crap! Seeing that 1 bar is about 14.5psi, that's 580psi!
Perhaps you meant psi for the tyres, hey? Unless you're going to use them as H2 storage
