I’m guilty of #10. Simply because I’ve found that most people can’t count & don’t know the rules of a 4 way stop. It’s just safer.
At a 4 way stop?
ALWAYS look at who’s already there before you get there. That way you get there - you stop - you go.
Nothing is worse than 4 morons pulling up to a 4 way stop sign and then wondering who got there first. Wondering who should go.
I often see someone at a 4 way first. But since they weren’t paying attention, I pull out first while they are still stuck on stupid.
