When you and another car come to an unmarked intersection in a residential area, and the other car gets there a few seconds before you do and stops, what do you do?

I glance at the other drive with a small nod and just proceed on without stopping. That other person is already stopped, and it seems to me that it’s a waste of time for you to take the time to stop too, while they wait, and then come to a decision as to who goes first. It has nothing to do with who is on the right or the left. The decision seems to fall to who has the guts to go first. Which is usually me. But sometimes you both do, then you have that start / stop situation. So you spend 8 seconds figuring that BS out.
Anyway, it’s much quicker for the non-stopped person to just go on and get it out of the way in 2 seconds or less.

When I get there first and stop, I have absolutely no problem with the other guy not stopping too—as long as I can tell (s)he was actually aware that I was there. Then it’s a mutual agreement.
However, if they just blaze through without a look, left or right, that pisses me off. If I hadn’t stopped, they probably would have T-boned me.

Any other unspoken traffic communications you wish to discuss? If not, we can talk about waffles, if you want. It’s social and it’s Saturday.
