I just read about a NHTSA probe or study that’s been upgraded for unexplained braking on Honda Insights. This unexplained sharp automated braking has happened at least half a dozen times in my car. There was never anything in or near the vehicle path that would explain the braking. It was always good weather (no hazard road conditions). In every instance it was a brief but sharp braking (with a loud audible beep beep beep). Three times it occurred within the same 1/4 mile stretch of road, which was a slight decline followed by a slight incline (at the time I was thinking that somehow the optical camera system was picking up some reflected or refracted light from the road or highway markings). But that seems unlikely, and in any case, Louisiana roads, being as horrible as they are, there’s no fresh marking paint or other reflective coatings anywhere on the road. I also wondered if maybe it was caused by interference from other radar or radio signals.
