Well, actually I once talked with my kid's school bus driver (he has 20 years on the job) and he told me that several attempts have been made, and the main reason they do not have them is not traffic regulations, or the size of the bus.....but the use the kids give to them.
In short.....they use the seat belts as weapons.
1. They used them as whips, and the metallic latches have proven to be very dangerous to make cuts, puncture eyes and the sort.
2. They use them as strangle devices, putting them around the necks of other children.
3. Is almost impossible to make them use the belts.
Even if they are there, there is no way to make the kids use them. They try a system that would not allow the bus to accelerate until all the seat belts were being used......2 problems, the driver would have to click all of the ones on empty seats (or sensors must be used on the seats), and the other one is that after the inspection some kids would take them off.....in short the bus would never depart.
According to these driver, they are thinking in California, US, to use something sort of the things you use on a ride on Disney (you know these things that come from the top, above your shoulders and get your chest and abdomen, which would function automatically, but the main concern is that they can stuck in an accident, and need a control pannel to open/close specific ones on every bus stop.
Believe it or not, the kids are the problem....and if you think about it makes sense.....I have one kid only and is a nightmare to make him use the seat belt in our car. Imagine trying to do so with 20 or 30 (i will just become plain crazy). And you have to see what are the uses that he give to the seat belt....I mean the glass is there yet because is thick.
You get the idea ;)
