Agreed. They’ve been in my Audis for 15 years, and the one American car (Tesla) thought I bought in that time period also had the feature, albeit that one had a phantom braking problem that the Audis did not, and I never felt quite confident in its ability to stop me in time to prevent an accident the way I did with the German cars. No real data, just feel of the system while driving.
I find that the latest Audi is a little overly aggressive when parking near a bush - it’s come on and slammed me to a halt almost a dozen times over the past two years while I was parking but still a solid 10cm from any impact, but obviously at parking speeds the words “slam to a halt” are a little overly dramatic. But overall, I’m a huge fan of these systems, and the data shows they help inattentive drivers on the highway.
