Really? An accident between two large cars is generally safer than one between two small cars.

It may make collision between cars safer, but it makes collision with non-cars deadlier for the people outside the car.

The general trend for pedestrian and cycling deaths is up in the US, because increasingly popular SUVs and crossovers strike a person higher on the body, and also are more likely to push a person under the car towards the wheels or forward where they’ll be run over again, rather than over the hood.

I don't disagree with you, and I'm not sure why you think I do?

Err in frontal collisions, maybe? But in pretty much every other case, having something with more kinetic energy will product more harm - it's physics after all. You don't see cyclists killing each others' a lot after all.
