I never thought about a sudden change in brake compound affecting the AEB system and its calibrations. I’ve always tried to stay OEM or comparable aftermarket pads. For example, I swapped my pads on my GTI for some EBC’s mostly because of brake dust. They performed very well, but I also had sticky tires. I have noticed I was able to find parts much more easily with that car than I have my Mazda. And with how many parts revisions I’ve seen for that one car I’d believe that they demand a lot in parts manufacturing. I guess it comes with the territory when they do something like the global MQB platform where parts are so easily shared.

In 6 years and 150,000 miles I only had one incident of a false positive where the car braked for whatever the system saw as an obstacle. Fortunately, no one was behind me but it was a route I traveled every day and it happened early on (~40,000 miles). My newer Mazda has the whole camera setup etc and definitely triggers if with the adaptive cruise if someone in the lane next to me brakes or slows down so I can see the overly sensitive reactions making people angry.

For the headlights, I don’t think factory cars are much of an issue. Now that matrix style lights are making their way here we should be able to learn a lot from Europe.

Thanks for the insightful reply! It’s cool to see stuff like this.
