Off topic and barely relevant to the improvement of driving safety.
If you want better driving safety, you want better driver training
I agree wholeheartedly with the need for better driver training.
However, the problems remain. For example, there's always going to be some jackass driving like a maniac, weaving in and out of traffic, trying to shave a minute off of his commute. The fact that he's a well-trained jackass is irrelevant if he cuts you off or runs a stoplight.
And no matter how well-trained a driver might be, one cannot discount the problems caused by lack of vehicle maintenance. Just yesterday, I was at a stoplight and I looked at passenger-side rear wheel of the monster truck to my left, and the tire was bald to the point of showing wires. (OK, a well-trained driver would be one who is smart enough to know not to drive on such dangerous tires -- but the argument always presented is, "I can't afford a replacement, and I need my car to get to work ..." The argument is bogus, of course ..)
I'd love to see much more stringent driver training. But between the lack of funding on all levels for such things, and the ridiculous idea that a 16-year-old kid is mature enough to drive a car, unfortunately it won't happen.
Speed limits actually hinder driving safety more often than they help.
