At least with cars, you know what an unsafe car can do (kill you) and it still took Ralph Nader's book and citizen pressure to set up a federal agency to oversee car safety. Also, even when most people know that seatbelts are a good idea, we still have seatbelt laws because they mean fewer people die.
