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.

You are correct. First reports seemed to indicate that the bus flipped sideways over the rail, but pictures show that not to be the case.

Air bags and safety belts in cars were origially designed to work best in a frontal crash, but now they are looking at impacts from the side.

Another thought: Headrests in cars are not so much for resting your head as they are to prevent whiplash if you get rear ended.
