if you are the car causing a long line of traffic, and you are going significantly below the speed limit (10mph or more below), and we're driving through very hilly, no-pass areas, please, pull off the side of the road as soon as its safe to do so, and let everyone else by.
please, do not slam on the brakes to stop at a yellow light. by this, I don't mean "oh the light is yellow, I need to slow down so I can stop when its red" but "stop-on-a-dime but the light is still yellow and if anyone behind you didn't have new brakes, there was just a wreck 3 cars back"
do not pull out of a gas station parking lot into the rear passenger tire of another car, then scream that its THEIR fault that your headlight is now broken. Teen drivers actually are not automatically in the wrong

(I was the 16 year old, and it was my rear passenger tire...her insurance paid)
Cops...do not give me a ticket for running a red light when I did indeed stop, for a full minute, before making my right turn. Telling me I ran a light, to which I responded "No, if I'd run it, I would've wrecked with *described other vehicle" then stating "Oh, well you were
going to"...since when did you receive mind-reading powers? It doesn't matter if I was "going to" stop or not, I did stop and that is the point. You can NOT ticket for
assumed intent.
I can't believe no one's mentioned this simple rule:
Do NOT shave your hoo-ha while driving.

this reminds me...an adult novelty store my friend used to work at sold a particular item that made her want to gather license plate numbers and driver's license numbers...something normally battery-operated for a lonely woman's recreation - plugged into the cigarette lighter instead of using batteries...
Please, if you MUST use this item, either be the passenger (with a non-distracted driver) or pull over and do what you need to do before resuming your drive...I really, really don't want you to try driving while doing this
