Not to nitpick, but that means if you sample randomly then you're going to find that the great majority of Americans have, in fact, driven less than 500k miles in their life.
Also I don't think that's correct; that's a ton of driving! I strongly suspect the number you're citing is the number of miles an average American spends in a road vehicle, not actually driving it. But that counts the same "car-mile" multiple times for all the occupants, when the statistic we're arguing about right now is about the vehicle, not the occupants.
