There is an Unconsious regulation with 4 way intersections with no stop. Whichever car was there first, goes first...They are usually intersection where little traffic is found, so rare occasions make for 4 cars there at once.

as far as i know that is not quite true... OK, i guess i learned in Texas, so maybe it's different in your state.
but as far as i know, the rule at a 4-way is whoever arrives first goes first,
but with a simultaneous stop the car on the right has right of way - i guess if you have 4 cars all stop at the same time, someone has to wave the others on... i think it's actually a law (but this may vary by state)
