2. If they wave for me to go first, accept their offer. Sometimes I don’t have to waive people through because you can tell by how quickly they approach the intersection. They’re obviously in a bigger hurry and they’re not even going to stop.

But sometimes you both arrive at the same time. I will always waive them through (see #1), but if they waive me through as a counteroffer I always accept. I’m not going to get into a back and forth waiving contest.

These two simple rules make life easier although you will wind up at your destination 5 seconds later, on average.

The fact this isn't widely known and reflexively followed is an INDICTMENT on immigration

Also to add to your OP:

The real question is when you both get there first, and it is clear that the driver on the right does not understand the "right goes first" rule. As a rule, I evaluate IMMEDIATELY whether that person understands the rule or not (based on their hesitation to move/facial expression/etc) and if I determine that they don't KNOW THE RULE like their fucking birthday, I put the gas pedal to the mat.
