> What evidence do you have that vehicles over a certain size and power are inherently more dangerous?

Basic physics and historical collision data collected over decades.

But don't take my word for it! Look up your local official collision data -- how many pedestrians have killed people inside a four-wheel vehicle? What about the other way around? Now repeat for cyclists, mopeds/motorcycles, and other four-wheeled vehicles.

The heavier vehicle kills the lighter vehicle, primarily because of momentum.
