Why not line up behind the last car in the center of the rightmost left turn lane?

Cars are backed up for 1/2 mile, so I would have to ride backwards for awhile (crossing over the traffic making a left) then U-turn past the previous light. Not practical.

Also, I am curious about the legality of riding to the front of the line at stop lights. I used to do it all the time on my motorcycle, although I always had superior acceleration to the cars.
