I think a human would drive over a kidnapper. Say your car is bullet proof. A man in a ski mask wielding a machine gun jumps in front of the road and orders you to stop. You refuse, he starts shooting at your car as you get near him (this is why I made your car bullet proof, to keep you alive but unequivocally demonstrate clear and present danger to you). In such a scenario, if your only escape route is over the dead body of the man in a ski mask, I bet a human will take that option.
