content: That's a pretty detailed fantasy you have there, but a valid point.  Sometimes you need to run over someone to get out of harms way.  Or maybe you just need to run a red light at 2am in a bad neighborhood when you see a group of  let's just call them "socioeconomically disadvantaged youths" approaching your car.  Better have that emergency override button ready.  These cars wil still need a steering wheel, gas, and brake pedals.
