Which brings us back to something that's easy to forget about the Peltzman Effect: It can be used to argue as much for more regulation as for less. Insurance companies, after all, have been fighting moral hazard for centuries, which is why they reward people who install burglar alarms or fill in their swimming pools (or punish people who don't do those things). And so, too, can the government — for example, by aggressively ticketing speeders, passing tougher drunken driving laws, or using a combination of carrots and sticks to help addicts get clean. There are better policy responses to moral hazard than mounting a spike on the steering wheel — or depriving addicts of a second chance at life.
