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.
