Depends on the vehicle. My 2014 Chevy pretensions the brakes, but doesn't apply meaningful force. My 2021 Hyundai alerts and pretensions as well. The two situations it's come on, I've been aware of the situation and actively moving to brake. Had I not actually applied braking, I believe the vehicle would have in my place. I somewhat suspect AEB on the Hyundai will lead to a collision, but at a significantly reduced speed. In other words, a fender bender instead of mangled mess.
