Intelligence test...

... I think they should make some drivers take a basic intelligence or common sense test when driving.

How many people will still insist on blocking an exit on traffic lights so when the opposite lights do turn green, no one can go anywhere, just because your light is on green doesn't automatically mean that you have to race up to the car in front, use a modicum (sp?) of common sense and leave a gap for the other stream of traffic when it is their turn to go.
