The thing is, none of this will address the real issue - drivers making bad decisions because they're ignorant. Education, testing, and consistent enforcement is how things get better.
Education and testing alone won't stop drivers from making mistakes. I would love to see more enforcement however.
"Education and testing alone won't stop drivers from making mistakes."
It very well could. Many of these mistakes are founded in ignorance. I see people doing things like passing on the right/shoulder and having no idea why that's dangerous. Or they have no idea what the vehicle dynamics are like for their car. Doing something like a skid pad or autocross (TireRack had a driver safety program associated with them) can really wake people up to their vehicles limitations. Things like following too closely on the road is generally not a true mistake, but a product of what is essentially negligence.
Edit: why disagree?
