I believe it is good to try these devices out but always when alone in the car.
My experience is that very few people are aware of how to use them, that includes ABS brakes.
What would an "advanced driver" autonomous car do...?

Any of the ADIs here able to tell how DVSA have altered their test criteria to suit ABS? As Astraist posted recently (and, AFAIK he's correct) best practice e-braking with ABS is to declutch.
How does that square with the old 'if it locks, release and reapply, and delutch just before stopping' principles?
Your 'standard' is how you drive alone, not how you drive during a test.

I earnestly believe that we are still at the stage of an awful lot of people releasing the brake pedal as soon as it starts to pulse. I was informed recently by an 'experienced' driver that this is what you are supposed to do!

I was lent a DVD about driving skills*, IIRC it included a demo of threshold braking instead of allowing the ABS to operate. If that was the case, fine for an expert driver who is prepared to brake and on a known good surface . . .

This is why cars now have emergency brake assist (so if you hit them suddenly, then lift off because the ABS has activated my understanding is this keeps the brakes applied even if you let go of the pedal - I'm not sure at what point the brakes then release? Maybe when you stop, or kick the throttle?)

IIRC Stressed Dave can demonstrate the difference in stopping distance between braking with ABS with hands on and off the steering wheel (if your hands are on the wheel, you'll tend to provide some steering input as the grip at different wheels varies slightly, so the car can't quite brake at its limit as it's also trying to allow you to steer. If you stay hands off the wheel, a yaw sensor keeps the car straight). I tried this on split-u grip at Porsche silverstone - emergency stop with 2 wheels on tarmac, 2 on "ice", hands off the wheel, and it's really /deep black magic/.
(similarly I tried driving over the kick plate hands off the wheels, and with a tiny bit of throttle applied the car is pulled straight with barely a twitch).

Blimey!
I had a post deleted by the moderator of one safety-related site after having the temerity suggest letting go of the wheel in a situation where the airbag is about to go off [to avoid the 'arms crossed over the airbag' issue]
Although that had been suggested by a World expert on airbags, it wasn't documented anywhere as good safety advice, apparently . . .

obviously if you need to steer, it's a bad idea to let go of the wheel. I wanted the opportunity to have a play in a safe environment and see exactly what the electronics did in a range of situations, and was quite pleasantly surprised (2007 Renaultsport Clio).

If the airbag is about to go off, steering won't help much

Meanwhile, w.r.t the original question NS recently had this https://www.newscientist.com/article/2098277-ai-needs-oversight-time-to-set-standards-for-autonomous-tech/.
Although how to define which AI needs oversight, when we are approaching "the internet of everything" is not addressed. Presumably they mean AI that is designed to (move and?) interact in some potentially damaging fashion, rather than something that learns how you like your tea.
