Wow, interesting event last night.
I have a 3-way intersection that I go through every day. One road goes straight through, and I follow that, but the majority of traffic follows a 45 degree turn to the right. There's a stoplight. This being Michigan, NOBODY signals their turns, so I just have to assume most people are turning right whether they're signaling or not, so when I get to the light and it's red, I move far left to avoid right hooks. This blocks straight traffic, but only for a few seconds; when the light goes green, I proceed, and as I get across the intersection I move back right to allow traffic behind me to pass and proceed.

Last night I was about 4rd in line at the light, the guy in front was going straight so the two right turners behind him couldn't proceed. I moved far left. Traffic took off, I went straight. As I was nearing the far side of the intersection, I was returned to the right tire track, and then I realized that the guy behind me was going straight and had decided to PASS ME ON THE RIGHT and even after I was moving to the right, he kept passing.

So I actually RAN A CAR OFF THE ROAD INTO THE DITCH. That was different, and kind of amusing, really. He just kept going and pulled back onto the road.
