I very much doubt AEB saves anything like as many lives as "studies" claim, for the simple reason the "studies" will not be able to account for the number of times AEB hauls on the anchors, unexpectedly, for no reason at all. This has happened to me 3 times in the last few years, fortunately with nobody behind me, and likely causes more accidents than it avoids. It will be good when it's production ready.

Lane keeping assistants can be pretty bad too. I have a relative with a 2018 VW that has a lane keeping function, and it's swerved the car out of nowhere a couple of times (or at least, maybe it made a small correction which startled the driver and caused them to swerve - either way it's a human interaction nightmare).

I think it's kept in some kind of standby mode at low speeds then kicks in automatically when over a certain speed, when IT chooses to kick in and can take the driver by surprise, the car tries to move to the centre of the lane (or what it thinks is the lane).

My VW has lane-keeping assist. In general I like it, because it had nudged me when I wasn't paying as much attention as I should have. But one failure mode is that it can detect shadows or other artifacts that it decides are lane markers. For example, at the right time of day hanging power lines will create a smooth curved shadow line on the road surface that the car will want to follow where ever they lead. It's not strong enough to yank the wheel out of my hands, but if I were briefly holding the wheel with my knee while reaching for something, it could get messy.

Right? These lane keep assists in every car I've used have been very gentle nudges. People talking about how their car was forced into another lane by the LKA really make me question how firmly they were holding on to the wheel.

This is some literal Looney Tunes stuff... But it's the future we live in.
