I want to talk about speed, because the next place that people listening to this will go, after automatically assuming that seat belts are the way to go, is speed. Obviously, speed is a factor in the severity of a crash.
My concern is that if people start to say we shouldn't allow school buses to go over a certain speed, you're going to create other conflicts on the road, because it's the variance in speed among the various vehicles that actually is a contributor to crashes. In the scenario of a two-lane road out in a rural area somewhere, if the school bus is going more slowly than the traffic behind it wants to go, that traffic will speed up to get around it, and that obviously creates conflicts, and so on.
Therefore, what should we be thinking about when people bring up the speed issue in trying to manage the severity of crashes?
