Measures of danger (at least in terms of fatality) does seem to scale with velocity squared. I do not find info on various measures of danger may scale with mass. There is a huge connection between fatality and vehicle size, at least up to the size of today's giant trucks and SUVs (I do not find buses nor semis included). Of course size is correlated with mass. Though, what I read, the danger of today's trucks and SUVs is due to the high front end impacting human bodies where they are more vulnerable (torso instead of legs) and then dragging them under instead of allowing them to go over. OTOH, stopping distance and reaction distance is linear with velocity.
