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.
I can see a small child in front of or behind my hatchback by looking out the windows, and its even easier with the backup camera.
A 5’-0" (152cm) person (who may be fully grown) was basically impossible to see over my old truck’s tailgate.
