There are also fewer buses needed to carry the same number of people, and they are operated by professional (and hopefully less distracted!) drivers.

I'm not sure a good data source, but I'd expect that the serious injury rate per person-mile of buses is much lower than that of private cars.

I don't have serious injury, but deaths per 100m passenger miles is 1/10th to 1/20th the rate for private passenger vehicles.

Rail is 1/2 the bus fatality rate.
