> In addition, the high center of gravity is more than compensated for by the total mass of the bus. In regular collisions, the bus is virtually guaranteed to be the heaviest vehicle involved, which carries an inherent measure of protection.

Maybe it's just the way I'm reading this, but it seems to me that the high center of gravity wouldn't really come into play in a crash (where the mass would certainly play a factor) unless it a very large vehicle hit the bus' side. I think the high center of gravity would be more of a factor on, for example, windy mountain roads where a vehicle with a high center of gravity would tip more easily.
