IANA automotive engineer, but I would assume that injuries from car-vs-pedestrian collisions are mostly due to impact velocity, and not due to momentum.

I wouldn’t be surprised if the higher-mass electric vehicles are more dangerous to other cars when involved in car-vs-car collisions, though.

Smaller cars are more likely to throw you up and over - still dangerous, but not as dangerous as a direct inelastic hit. Smaller cars have better visibility of pedestrians and so are more likely to see and thus avoid pedestrians.

If you take a direct hit with even a tiny car at faster than 30mph you are dead. However smaller cars make it somewhat less likely you take that direct hit.

Yeah — but when I hear people talking about how EVs are heavier, I assume that people are making a like-for-like model comparison.

In a similar body size, EVs tend to weigh more, due to all the extra battery.

IANA automotive engineer either. I'll quote national bureau of economic research:

> The probability of a fatality, conditional on a collision, is 0.19 percent -- or about one in five hundred. The authors find that being hit by a 1,000-pound heavier vehicle results in a 47 percent increase in the baseline probability of being killed in the accident...
