I hate it when in at a red light, the person behind me gets as close to my bumper as possible. Sometimes it looks like they aren’t even going to stop in time. When I stop I leave a normal amount of room in front of me. When they get close to me, I move up a few inches and wait to see if they move too. When they do, I move up another few inches and see how many times they will move up too. Its crazy how many time some people inch up at a red light with nowhere to go.
