When I finished a series of driving lessons and got my regular license 27 years ago the driving instructor offered some words of profound wisdom: "You might have your license but you really are still learning. You won't be a real driver until about two years from now when you have experienced winter, heavy rain, and all sorts of other conditions. You might have your license but you're still a beginner...and will be for a couple more years."
" "Most of them, believe it or not, know how to drive. The big challenge is getting them to pay attention to what they're doing when they're driving," says Hammack."
Truer words never spoken. Constant checks - in the mirrrors - a routine- defensive driving skills developed over time and experience - get them into agressive driving classes - let them find out on a controlled course what they are capable of or not.
