Lyzko: The purpose of cars though is not to kill. Guns etc. are something else now!
Guns are to defend. Cars serve as means of transport, guns provide safety. Different tool, different use.
Imagine non-killing but effective ammunition. Practical requirements are known: bullets with huge stopping power, but not penetrating. Incidentally, 2 or 3 decades ago the French designed and successfully tested exactly this kind of ammo. It looked like a squat bullet with concave curvature of the tip. Kinda heavy tack.
Never went to production, and if I recall well, for political reasons. Apparently this would greatly increase pressure on the right to carry, and 'we are not having this kind of thing'.
Makes one think, like.
Of course, even with this kind of ammo there would be accidents, read deaths. Same like with cars. Or baseball bats. Or alcohol.
