Let's consider the energy efficiency of moving a vehicle weighing about 2000kg to transport a person who weighs around 100kg. That's a ratio of vehicle to person of about 20:1.

A potential solution would be to give heavier cars worse crash ratings. This approach would take into account not only the safety of the occupants of the car but also the occupants of other vehicles.

I was going to ask who weighs 100kg, but then I looked it up at it turns out that the average male weight in the US is over 90kg(!) https://en.wikipedia.org/wiki/Human_body_weight#By_country

That's exactly how it works in the Euro NCAP ratings: https://www.euroncap.com/en/car-safety/the-ratings-explained...
