I fucking hate it when someone waves me through a 4 way stop. There are two scenarios. 1. It's already my turn. - I know it asshole, who made you the traffic director? 2. It's not my turn. - This is what really bugs me. If I go and midway through my decision, the other driver decides to go and hits me, I am liable because it wasn't my turn. The whole deal screws up the 4 way stop order of life and ultimately slows down the process.
