Right-turning vehicles on red lights are the worst, IMO. Many of them see that the right lane has a small gap, even if the left lane traffic is zooming past a speed, and they proceed to make the right turn, often forcing the vehicle on the right lane to brake, and sometimes brake hard, depending on how big that gap is. Yes, cars aren't supposed to make lane changes in an intersection, but the risk of someone doing so is high enough that I just won't take that chance.
