I had my first experience of one of Brighton's new Volvo buses today. They are roomy, have easy stairs, reassuring grab handles, comfortable seats: but I was astonished to see that the latter had all been fitted with seat belts. Bearing in mind that the chance of a bus passenger fatality is 13 million to 1 and the proportion of these that occur while the passenger is sitting down, even unbelted, must be vanishingly small, I can only imagine that Volvo must have had a lot of these seats surplus to its express coach production line.
Commonsense suggests that most injuries to bus passengers occur when they are getting on or off the bus. If the bus driver is to wait until every passenger is seated, and belted up, before moving off, and every passenger waits until the bus stops to unbelt, all the hard-won reductions in journey times will be shot to pieces.
I can also not make any sense of the warning notice on the back of every seat. I suppose we must attribute that to Swedish/English translation difficulties.
