>Jerks with fast cars, at least, are focused on driving. Maybe they are, maybe they aren't, but I doubt speed is a good predictor of attention or skill. Poor drivers have a greater risk of causing an accident than skilled drivers at all speeds. We still punish skilled drivers the same as poor drivers because it's hard to differentiate between them. Take a driver of unknown skill who's driving 1 standard deviation above the speed limit. He could be above-average, and be just as safe as an average driver going the speed limit. He could also be below-average and believe he's safe - but would actually need to go one standard deviation slower than the speed limit to match the safety limit of the skilled driver. So, we punish them both the same, because we can't know.
