An object travelling at a constant speed and direction may have no acceleration in its own reference frame, true. But it can absolutely accelerate another object in another reference frame.

I don’t know what “F=mv2/2” is but maybe you mean the equation for kinetic energy? KE = 1/2 mv^2

At any rate (ba-dum-tss), getting hit by cars sucks no matter how accurate the mass measurement is. The slower the better.

Exactly my point. Drivers need to me more engaged, aware of themselves and their surroundings, and less reliant on automacy.

If you want to take the human out the equation, that’s fine. Take the bus then.
