Killer Cars

Heavier cars are safer for their occupants, but more dangerous for all others. The baseline chance of being killed, given that you are in a collision, is one in 500. If you now increase the weight of one of the cars by 1,000 pounds you increase the chances of being killed in a collision by 50%. SUVs, pickups and minivans are still more deadly. This is an excellent reason to tax heavy vehicles.
