Thee are quite a few MORE that should be on the list. Most of them can be summed up simply: NOT knowing traffice laws and/or generally accepted rules of the road.

Forinstance, use the Left or passing lane to pass and then move back over especially if you see someone coming up behind you who may want to drive faster than you and pass you.

Which brings up another problem other than just knowing the laws, it's called driver judgement. Too many people can't judge relative speed of other drivers. It's a safe bet that if someone is coming up quickly behind you on an interste that they are driving faster than you are so you might want to consider moving to the right if and when safely possible.

People using "turning lanes" which are generally a one lane portion inbetween a 2 or 4 lane road. they are supposed to be for TURNING and you should enter and slow down and perhaps stop and then turn. They are NOt another lane for peole to drive long distances in.

Ever notice how the courtesy and quality of drivers on interstates changes with the seasons?

I really hate it when people almost come to a complete stop before getting into the left turn lane, or worse, they stop halfway between the turn lane and the regular lane to make their turn.
