I have no experience with that version, but I've experienced AEB driving
the 2022 Kia EV. It's always been responding to a false alarm. For
example, once on a 35 mph city street, the street had an oddball sudden
jog left and right. I think that put a parked car in the straight ahead
view of the camera system, and the brakes went on. At other times, I
could see and time a car slowing to turn into a driveway, but the camera
seemed to assume he was stopping in the road.

Anyway, if this technology becomes common, ISTM it might help reduce the
~1000 bicyclist and ~7000 pedestrian fatalities in a typical year.

 Seems to me that AEB system was designed for high/freeway use only.
A slow city street is a ludicrously complex environment for AEB at
the present state of the art.

I think you confuse "AEB" (Automatic Emergency Braking) with Adaptive Cruise Control; Seems you did not watch the linked video. On highway/freeway you rarely have pedestrians cross the road.
AEB currently has several false positives (plus as a "false negative" it cannot cope with the zig-zag bike route design of
<https://en.wikipedia.org/wiki/Protected_intersection> ).  As a pure safety feature, you normally cannot switch it off as a user.
But if you have possibility to compare AEB systems designed in 2018 with those from 2020 and those from 2025 you see massive improvements.
