Except that, E = 1/2 m v^2
. You can’t get rid of that m
. All else being equal, lethality scales linearly with vehicle weight. The safety features that exist are still for the occupants; there are crumple zones for decelerating another vehicle hitting head on, not foam padding for protecting pedestrians. Some features of trucks are extra bad for impacts, but a heavy EV is going to be worse than the same frame with less mass.
heck compare the cost of labour 40 years ago to now
