Pet Peeve

If you are driving on the freeway, and the person in the fast lane isn't going fast enough for you, do NOT move over to the slow lane and start flashing your high beams at the person driving over there. If you absolutely must flash your high beams and make a complete ass of yourself, do it in the fast lane.

By the same token, don't drive in the fast lane unless you are, at the very least, going faster than the traffic in the slow lane. And in general, don't get in the flippin' fast lane unless you are passing.

If people just obeyed basic traffic laws and used common sense while driving, road rage would never happen.
