A high-hooded truck or SUV is far more dangerous to the public than a small car, and a small car is more dangerous than a motorcycle, so a speeding ticket/liscense points/jail time for an SUV should be >4x more severe than a motorcycle doing the same violation, and bicycles should basically only recieve token fines.
The energy alone isn’t the whole story, the bike or low-hooded car is much more survivable because of the lower point of impact.
Multiply again by h_CM / h_CMRef where the denominator is the height of the center of mass of a typical sedan.
It just gets a little funky if, say, you’re driving a sprayer that is multiple times taller so you couldn’t collide with a reference vehicle anyway. Edge cases happen.
