Normal brain: Wait a minute. Increasing fines for the 1% can solve at most 1% of the speeding problem. Okay, the 1% number is polemical, but any solution to the problem of speeding must fall mostly on poorer people, because they are the majority.
Glowing brain: Why do we talk about speeding as a crime? Any economist would tell you that the optimal amount of speeding is nonzero, so it should be solved with a Pigovian tax equal to the negative externality. Since a rich speeding person does as much potential damage as a poor speeding person, the fine shouldn't depend on how rich you are. If you want a safety net, build a safety net, don't muck around with speeding fines.
Galactic brain: Is speeding that much of an externality though? If you go fast and cause a crash, you bear about half of the cost. If you don't cause a crash, no one bears the cost. It's not like pollution where the polluter bears a millionth of the cost. So it seems like selfish decision making, with average human level of loss aversion, should already deal with the problem of speeding. Why isn't that happening?
Buddha brain: People know the cost of a crash. Speeding happens because people misjudge the risk of a crash. So perceived risk, not cost, is the right variable to tweak if you want to fix speeding. Make enforcement of fines much more fast and certain, and you can solve speeding while lowering fines. The whole article about billionaires was a distraction from a distraction from a distraction.
