You see, in the new economy you don't even needs stalks!
I simply hit this Autopark button and then my car alternates between inching back & forth to sharply jerking the wheel every which way, and then lands itself in the spot.
All while taking 3x longer than a competent human parallel parker and with heart stopping near-misses of hitting the surround parked cards. Oh and curbs your rims 20% of the time.
Oh and as the human driver you are still responsible to monitor for passing pedestrians and bikers.
If it crashes it's because you weren't monitoring it closely enough. And if you hit the brakes to stop it, you are a wimp who doesn't trust the car which totally would have gotten it right if you let it.
