What happens when the auto braking engages? Does it just slam the brakes on and stop dead? Wouldn't that be a big risk of you getting rear ended by someone behi

  Yes, it goes into full anti-lock braking, but it only does this at the very last possible second it can be done without a collision - the driver usually gets enough time hearing an audible alarm to stop, provided there is enough time. I haven’t heard of any rear end accidents due to false alarms with AEB, though that doesn’t mean they don’t exist. I’d guess the system is tuned to need enough confidence that a forward collision is likely to engage braking, knowing of the potential consequences of suddenly and dramatically stopping.

  In my Passat it just barely taps the brakes rapidly to get your attention, I've never had it go further then that but in theory it will lock them up if you don't respond. If it detects someone in the lane you are about to merge into, it cuts off the power steering for a millisecond, just long enough for you to notice the car in your blind spot but not long enough to prevent you from going into the lane if you really want to. It's pretty close to perfect in my opinion.

  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.
