It stops applying power to the wheels automatically if you unbuckle or lift yourself off the seat, once AutoPilot goes into the “Take over immediately” state. Of course the human who is actually driving can re-apply power at any time. The car will not pull over unless you leave it in the full-on alarm state for a significant amount of time. The alarm is pretty loud. It’s not a state a driver would leave the car in unless they were incapacitated or doing it intentionally.
