I agree with Lala. I turn left at a very bad intersection, and if the timing isn't "just right" for me to get over to the turn lane, I go through the intersection to the little "island" on the other side, stop and turn my bike to the left, and wait for that light to turn green. If I go through one that's totally insane, I can always get off and walk it in the crosswalk. While you're waiting for the lights, you can get a drink or munch a snack bar.
