  As with so many other things, average isn't really a good measure here. And unfortunately I don't think mode or median are really relevant either. It's the instantaneous speed that causes problems. Zooming up the block in a minute at 40 mph and then sitting at a red light for 3, your average was 10, but if you'd hit something, the damage you'd have done would be a lot worse.
