I don't know about you, but if I'm that California guy, I'm probably pretty shaken up by being trapped inside a hurtling mass of malevolent steel, and I'm thinking of suing. And frankly, if I'm a Prius owner with gambling debts, I'm thinking pretty seriously right now of a controlled crash followed quickly by a lawsuit. (Also, if I'm an irresponsible teenager whose parents have a Prius, I'm thinking of taking it for the ultimate joy ride, and then just blaming the car.)
Of course, I am none of these people. But if I were, WHO COULD STOP ME.
