I know of a former coworker who had been struck from behind at a left turn lane by a motorist transporting a new car to a dealership. My coworker suffered a dislocated shoulder and back injuries. That was years ago. He's ok now.
When I look at that intersection, it seemed so busy with cars, it looked like it would be safe for a bicycle to wait and turn left like all the other cars. But he was there early in the morning when traffic was swift but not congested. I choose to go straight and then turn my bike leftward on the other side of the intersection.
Bad drivers are everywhere. Even when I do this, I still get drivers making right turns trying to race with me through the intersection when I get my light.
