Too bad all drivers aren't like aley!
For those that misunderstood, I *don't* get in front of the front car. I'm generally diagonally to the front right. And the turn I make is wide. The cars will be cutting into the turn more than me.
But I do agree about drivers having one more thing to worry about - not knowing what I'll be doing.
I generally don't do this if the line of cars is less than 6-7 or so. From reading other threads, there seem to be some agreement that it's ok to do if it'll prevent you from sitting through an extra light cycle.
