Reminders of scale aside, I posit that the limit for vehicles needn't be speed or size, but braking distance. If a manufacturer can make a 6600 pound SUV that stops from 75 mph in the same distance that a 3300 pound sports car with track brakes and extra grippy, super-wide tires, brakes from 75, I say more power to them.
Until then, this metric will naturally lead manufacturers to downsize, and for the ones who still produce SUV's anyway, they will need to be as good at stopping as regular cars, which might make them more cost-prohibitive and dissuade their ownership via market pressure.
After all, it's not speed or size that cause automotive fatalities, it's cars being unable to stop in time before impacting other vehicles, pedestrians, or impassible barriers.
Note that I did not actually claim that it was the third leading cause of death, just that it eclipses auto deaths and firearm deaths combined and doubled.
