I go with the flow of traffic, I tend to pick a lane and stay in it. Above all I try to be as courteous as possible to other drivers. I will say that those that try to change lanes without signalling won't get a buffer from me, but if they do signal I slow down to make room for them. There's a reason the DMV makes sure that you use the signals properly, please do so.

Granted, I also make sure and leave so tat I can get to my destination well ahead of time.
