A motorcyclist has to drive as if everybody else on the road is out to kill him. A few of them are, and many of those who aren’t are just as dangerous—because the only thing that can alter their careless, ingrained driving habits is a threat of punishment, either legal or physical, and there is nothing about a motorcycle to threaten any man in a car. A bike is totally vulnerable; its only defense is maneuverability, and every accident is potentially fatal—especially on a freeway, where there is no room to fall without being run over almost instantly.
