I guess the AEB works at reducing accidents because it IS autonomous and does not "improve performance".
BTW the KPI is reduction in insurance cost.
First rule of winter driving is don't touch the brake.
Depending on the conditions that can be fairly acceptable, for purposes of drifting a modern car's breaks suck a lot thanks to those two (the handbrake is free game tho)
That doesn't sound right. Pretty much all cars today have ABS, which should make sure that you don't lose traction.
When I first drove a car with ABS in winter I was amazed how well the breaks worked in bad conditions -- of course the car would take a lot longer to come to a stop, but it did come to a stop.
The other thing is to accelerate through turns - it helps maintain traction.
These are edge cases though, and ABS does generally improve braking distances. At the very least, it gives you a much better chance of avoiding the obstacle in your path.
You can absolutely brake, you just have to be smooth and gradual.
That's not the ideal outcome but it's still a net win, no?
So from a safety standpoint, that is a not a win.

In AEB systems the emphasis is on dramatic interventions when calamity is imminent. So for example rather than gently brake pre-emptively because you seem to be getting a bit close, AEB is focused on braking very hard at the last moment, this doesn't feel like your skill saved you, it feels (correctly) as if the automated systems kicked in to avoid a crash.
No so long ago I was caught out not paying enough attention approaching a roundabout at a creek crossing on a rainy day. It dawned what I hadn't allowed for the slippery road conditions on that day when the car started to slide towards the creek rather than go the direction I was steering. I'm by no means an expert driver, but I've spun a car off a dirt road into the bush a few times in my miss-spent youth, enough to know when I've lost control beyond recovery. I only had a few meters before a collision, but another thing I learnt during that miss-spent youth is if you can arrange to slide into a guard rail sideways so the load is spread along the entire side, if your speed is low enough you might get away with no panel beating at all. So I eased off the brakes to get maximum steerage.
Then the car noticed the steering wheels had lost traction, and the ESP cut in. ESP boils down to steering with the brakes and engine - sort of like a handbrake turn, but the brakes are applied to a front and a rear wheel on opposing sides and the engine powers the other two. There is no way to do it manually. Turns out it's amazingly effective, as it both slows you down and gets the car pointing in the right direction.
There was no accident that day.
I've stomped on the brakes quite a few times to see what ABS in action feels like. I reckon I can do a better job manually. But there is no way I'd drive so crazily that ESP cut in on anything but a skid pan. Besides, there is no point. I know I could never do as good a job, because as I said, there is no way to manually replicate what ESP does. Having said that, a good racing driver will do better without ESP because they get the car pointing in the right direction before it starts skidding - but that requires paying more attention than I was at the time.
What you refer to as ESP is usually known as ESC where I live and it's also been mandatory here for a while, agreed that it is pretty incredible. I can definitely see it giving people a false sense of security especially in low traction conditions like snow/ice/rain.
