I kind of think that EVERYONE who drives, no matter WHAT age, should have to have a driver's liscence before they are even allowed to purchase/insure a car. I know young teenagers like to buy a car before they get their liscence, but in a case like that maybe a parent should be responsible? Also, why not make everyone take a mandatory sight check at the time of getting a liscence? It isn't hard to have a sight chart. Anyone's eyesight can fail.. I don't understand why we only get tested once and forget it. I've seen a LOT of horrible drivers, and they certainly weren't all past a certain age!!!
