You don't have to believe that speed increases the risk of death or injury or serious property damage in an accident, and also increases the risk of having an accident in the first place. You do not have to understand the concept of momentum and how that affects what happens in an accident. Believe in your airbag, believe in your reflexes. Hooray for you.
I can't possibly convince you--you don't have the math. You believe you're as safe driving at 85 mph as 45. Okay, fine. Believe that. Ignore physics, ignore the coefficients of friction, ignore the fact that bootleg auto parts are showing up in convincing packaging in auto part retailers across the country. Metal fatigue doesn't happen to your cars, and mechanical problems will only happen when you're parked. Trust your reflexes. Obviously you have a reaction time several orders of magnitude better than we poor common folk.
I hope you do not drive in my state.
Oh, I certainly have the math, and am quite well acquainted with each physics, and physiology. ...And what I said was, your list of objections would apply to your standards at 45.
I also have experience driving at over 100.
The fact is that driving habits have far more to do with the accident rates than simple speed - as well as speed DIFFERNTIAL. There is a REASON that deaths per mile travelled went DOWN when the interstate speed-limit was raised.
Your original argument, that I responded to, was that even under ideal conditions, 85 was not controllable with mere human reflexes "even under perfect conditions". That is simply false. To even begin to argue, you had to introduce all kinds of other factors not related to human reflexes.
MILLIONS of people travel at such speeds daily without having an accident, or even a close call - unless you are saying that Germans are an inherently superior race. :)
