Of course, in my opinion, we should have in place a system where folks are re-tested every few years. The laws are *always* changing – those legislators have to justify their existence somehow – and are you really sure you know what the current thinking is on the correct way to handle a driving situation?
Even if your approach *is* the best, if it is unexpected as far as the other drivers are concerned then it is *you* who are the hazard.
What do you do when a schoolbus has its amber lights flashing? What about its red lights? On a divided highway? I see people doing the wrong thing all the time, they are endangering EVERYBODY’s lives.
