“”Don’t you just love it when you come to an intersection with a 4-way stop and some do-gooder waves you ahead when it’s not your turn? Who do they think they are?””
Hanlon’s Razor. Most of the time it’s because they don’t know the laws on 4-ways and they’re trying to get YOU to go ahead so they can go. If both cars reach the stop sign at the same time... the driver on the right is supposed to go first. Clueless drivers will just sit there or wave the other driver on.
When it happens, I just have to wonder if it isn’t somebody’s idea of a public “random act of kindness”, so I’ll just sit there and wait for them get the hell out of the way, and sometimes they’ll give me the evil eye as they pass through!
