The auto-braking collision avoidance system on my 2023 Mazda CX-5 actually is exactly what caused my first collision in 20 years. I was slowing down to avoid a car that was turning off, the auto-braking decided I wasn't slowing enough (or, I might have just let go of the brake) and it proceeded to slam on the brakes bringing me to a full stop on a busy road, leading to me being rear-ended. At no time was any of that necessary. I've also had the auto-braking engage (on multiple cars) because of random debris in the road, or seemingly no reason at all.

Granted, I'm sure this will improve over time. But for the past 5ish years, all my experiences with auto-braking have been dangerously negative.

I've never driven a car with auto braking. I've been yapped at many a time for lane "departures" that were not lanes (concrete grooves on the highway being the primary culprit) and sometimes not even real (that "lane" is the shadow of a nearby power wire.) I've also seen the adaptive cruise control appear to fail once when two cars simultaneously changed into my lane, one from each side. It still had a moment it could have acted so I can't conclusively say it failed. It also fails to recognize cars with too great a speed difference.

The classical caveat of any fully automated system - it works well when everyone has it.

The most likely explanation is that you were tailgating.

So what if they were?

A system that takes driving too close and turns it into something more dangerous is not a good thing.

[konschubert]

There is no actually no indication that Waymo cars are making tailgating even more dangerous

[Dylan16807]

Huh? Aren't we talking about the anecdote above, where they were following a turning car, then automatic emergency braking kicked in and they got rear-ended? No waymo involved.

[konschubert]

I was thinking about the waymo incidents.
