Some cars brake for you as soon as they think you’re going to crash (if you have your foot on the accelerator, or even on the brake if the car doesn’t believe you’ll be able to stop in time. Fords especially will do this, usually in relation to adaptive cruise control, and reverse brake assist. You can turn that setting off, I believe but it is meant to prevent a crash, or collision. In fact, Ford’s Bluecruise assisted driving feature was phantom braking to the point there was a recall about it because it was braking with nothing obstructing the road. I believe they also just updated it so that the accelerator press will override the bluecruise without disengaging it in like the 1.5 update which happened this year.

But I was thinking you were correcting me about autopilot for planes and I was confused.
