They may have some promising data, but from what I've seen driving 2019 and 2021 model vehicles from Ford and Mazda, they are not even close to ready for prime-time.
I find both vehicles consistently falsely trigger the red-flashing-and-loud-beeping "COLLISION ALERT!!" dashboard warning to both small pavement cracks/potholes, and also to vehicles parked on the outside of a curve. This has happened at least a dozen times in the past ~30,000 miles driven. If those were instead automatic braking events, they would have caused an unnecessary rear-end accident least three times, as if I'd surprise "brake-checked" the driver behind me.
Yet, in an ACTUAL near-collision situation a few weeks ago, driving at night ~50mph on a rural road, a car ran a red light right in front of me, and I had to full-on threshold brake, years of road-race training reflexes kicking in before I was even aware of it. I barely avoided a collision, stopping with smoking brakes and a passenger with a pulled back muscle from having been not quite square with the seatbelt, my front bumper about a meter from their driver's door.
The car never made a peep — it completely missed the incident.
Of course, a working automatic braking system might have helped anyone in that situation, including me if I'd been a bit more sleepy or distracted. BUT IT DID NOT EVEN DETECT IT. The track record for the past 30,000+ miles is:
— 100% false positives — 100% false negatives
These 'collision detection systems' are 2-5 years newer than the systems AAA tested, yet the track record is awful. IDK what they are smoking but I do not want any.
I doubt the automakers are somehow holding back some magic solution, and would give them a LOT more time to get it right.
Just because a technology is promising does not mean it is ready to provide a benefit released in the wild on fast-moving multi-ton vehicles.
