I will often wait in the queue at a stop light, but it's a judgement call. There will be people whose views I respect who would consider flamethrowing... but around here, generally there are 2-3 cars in the queue... often more on the other side, some of whom are going to be taking lefts. Oh, and usually one of the ones in my queue are making lefts - there's no dedicated left hand turn.

So, I scoot to teh front where the cars on both sides can see me, and right-turners can get by behind me. If the cars in the queue are going straight, they're all by me by the time I'm across; if they're going left, I'm across and have my lane position and I'm past the opposing-direction queue before soembody would even want to squeezy by me, so they can pass me safely instead.

This is totally intersection-specific. When in doubt - or at a new intersection - I'm a vehicle. I'm in the queue. Even then, though, there's the issue of driver who expects me to be in the shoulder (or to pull to the front), so they pull along beside me. Usually I still stick to that spot, because one of my Primary Principles is "don't make 'em pass me twice."

(I've most recently bellowed at wild turkeys. The drivers have been mostly okay.)
