There is really no point in arguing with someone who doesn't understand basic physics, so I'm not going to. If you really believe what you wrote I suggest you go read some books.
I understand basic physics just fine. If you run into a brick wall with your car at 1mph, the energy of the impact is no different than hitting a vehicle going 65mph when you are traveling 66mph.
Again, speed, in and of itself, is not the issue. Speed differential is.
BTW, I'm not a little old lady who never drives fast. I raced autocross for years in BMW 2002s and even did some rally racing when I lived in the south west. I know a thing or two about driving fast. There is a place and a time, and its not when you are on the road with other people, period.
I don't think anyone is claiming you are old, female or slow. The BMW 2002 is a great car; I'd love to have one. Personally, I'm a big fan of the E46 chassis; especially those of the S54-powered variety. Since you have track experience, I am surprised by your position.
I have plenty of track time as well. All road course; 80% of it in rear-engined cars. I don't require a book to tell me what is going to happen if I exceed the limit of adhesion. I've exceeded it on more than one occasion; the line between trail braking and snap oversteer being rather thin in a car boasting a 40/60 weight distribution.
...2nd only to drunk driving, the largest cause of fatalities on the road was people speeding and loosing control of their car.
Speed is not what causes injury. The difference between walking away from a collision and becoming a statistic is, again, speed differential. Injury is sustained when forward momentum is abruptly altered or stopped, entirely.
The real problem is people don't have respect for what a vehicle can do. Try being a first responder to some of these crashes, where you come up to half a body, laying on the cold asphalt grasping for air and begging for you to help, but all you can do is watch them die. THEN tell me speeding is harmless.
See above.
In concert with your point of view; please don't misunderstand me. I agree 100% that public roads are *not* the place to be playing boy-racer or competing in the Stoplight GT. As you stated, "keep it on the track."
By the same token; I would suggest that an overwhelming majority of drivers on US roads have absolute no clue how to drive. If you have track experience; especially on rally circuits; you understand. I would expect you to agree with my opinion.
Accidents like those you are describing are horrible things, no doubt, but they are not the result of "speeding." They are the result of driver ignorance. Ignorance both of their vehicle's capabilities and their own.
That ignorance is to be expected when we place more emphasis on teaching little Johnny to parallel park instead of recover on a wet skid pad.
In Finland, if memory serves, it takes about three years to get a full drivers license and exhaustive lessons in car control.
Here? Takes about five minutes. Know what a stop sign is? Check. Slow down in preparation for a stop when confronted with a yellow light? Check. Put your seat belt on? Check.
That last one is the most important part of our drivers education program because with the amount of training 16 year old's get in this country, that seat belt is probably going to be needed.
You appear to have plenty of experience with the result of this ignorance. The solution is to fix the training, not vilify "speeding" as the be-all, end-all cause of automotive-related fatalities.
