The jumping back and forth lanes thing is poor planning and in stop and go traffic, non productive for the most part.

Stopping on top of / past the _BIG WHITE STOP BAR_ at a traffic light. The bar is there to hold traffic back so others turning can make it past with something like a long trailer. If anyone here stops on / past the bar, please state your logic.

Don't be surprised if I place my car / truck microns from your front bumper as I turn.. .
