“Have you ever noticed when you’re driving,” the comedian George Carlin commented, “that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?”
True enough. But when you think for a moment about Carlin’s quip, how could it be otherwise? You’ve made a decision about the appropriate speed for the driving conditions, so by definition everybody else is driving at a speed that you regard as inappropriate.
If I am driving at 70 and pass a car doing 60, perhaps my view should be, “Hmm, the average opinion on this road is that the right speed is 65.” Almost nobody actually thinks like this, however. Why not?
