"Stop at stop signs in parking lots"
Whoa there, skippy. That ain't true. You DO have to stop at those stop signs, because the rules of the road apply in parking lots the same as they do on a street. While your city or municipality might not have laws to enforce this, many DO. And if you peg a pedestrian while blasting through one of these stop signs, you're going to be in a world of trouble either way.
