It's like the thought experiment of replacing seat belts with a spike sticking out of the steering wheel.
That will guarantee that car accidents and deaths drop dramatically.

Historical evidence suggests that there would indeed be fewer accidents but more car drivers would die (because even quite trivial bumps would be fatal), though pedestrians and cyclists would be safer. As someone who chooses not to drive, that sounds pretty good to me.
