My pet driving peeve is when people in small light cars zoom up to a stop sign to stop.  It looks like they're going to run the stop sigh right in front of you.  I drive a big car.  1973 Olds 98.
Another time, a girl did a rolling stop directly in front of me while I was driving my '69 Olds Delta 88.  I slammed on the brakes, and could see her looking at me with complete surprise.  I was going 35 mph and stopped long before hitting her broadside.  But I separated both front tires when I did that, and had to buy two new front tires.
I never trust stop signs, not after some of the experiences I've had with them.  Drivers just don't pay attention!!!!  
Everytime I drive I think about the "War" song...low rider.  Drive a little slower...
