4 way stops are great until some A hole screws up the process trying to be nice..... And then there are the ones that just have to jump their turn.......
Had that happen recently.
4 way stop and I stop but a woman on my left dips the front end then nails it (you know those) they kind of pretend to stop but just can't get themselves to allow you your right of way.
Left her in a cloud so thick she couldn't see to go anyway.:D
