I thought the US had a “FIFO” rule for 4 way stop signs? I had to drive through Nevada and Arizona last year so read up on the rules.

Keeping track of which cars entered at what time was kind of stressful and I’m pretty sure I didn’t do a good job of it.

The US has a FIFO rule but it only applies once you reach the stop sign itself, so the FIFO is never very deep. Yielding to the person to your right is the tiebreaker if you get there at exactly the same time.

I have seen an increased number of drivers have no idea how to handle 4-way stops, but the rule is relatively simple in practice.
