Though it might not be obvious to American drivers, this is the solution. There will always be that driver who attempts to change lanes mid-intersection to get into an opening first; that's part of what motivates American drivers to enter the intersection before their exit is clear. (Lane changes within the intersection are illegal in the US, but rarely enforced.) American drivers also accelerate quickly only to brake desperately, which creates "openings" for rapid lane changes as well as more trouble staying out of intersections. In spite of higher accidents, more fuel costs, and even occasional tickets (for not signalling properly), this is a persistent driver behavior in many areas like California.
