Why don’t trains or buses have seat-belts?
The fatality rate for school busses is 0.2 per 100 million miles traveled. The fatality rate for cars is around 1 to 1.5. Buses are already roughly 5x safer than cars, so seat belts aren't worth the bother.
The Short Answer
The fatality rate for school busses is 0.2 per 100 million miles traveled. The fatality rate for cars is around 1 to 1.5. Buses are already roughly 5x safer than cars, so seat belts aren't worth the bother. The fatality rate for long-haul train passengers is 0.15 per *billion* passenger miles. Trains are a hundred times safer than cars. The vast majority of train deaths are pedestrians and vehicles that trains slam into.
