> It may not fit your narrative but Front Radar electronics/firmware filter out stationary object ONLY if they are outside the vehicle trajectory envelope. The first challenge is that cars do not always travel in a straight line, so the "vehicle trajectory envelope" is ill-defined. At minimum, the radar needs to be steered (electronically) to match the anticipated vehicle path. However, the anticipated path does not necessarily match the actual path. The second challenge is the size of the target. If you re-watch the video, you'll notice that the pickup is sideways, and appears to have collided with a sedan prior to the Tesla arriving. In other words, the radar target is approximately 2x to 3x the angular width of a normal vehicle. If you filter the radar returns to eliminate wide stationary objects (to, for example, reduce phantom braking caused by overpasses), you necessarily handicap it when detecting a truck parked sideways on the road. Putting on my ML engineer hat: One of the common themes in examples where Teslas fail to brake is that the target is stationary and very wide: A semi truck crossing a not-limited-access highway, a crashed pickup turned sideways in the lane, etc. etc. etc. > EuroNCAP tests for AEB include both moving targets AND stationary targets Your link shows only scenarios where the target is exactly positioned along the centerline of the vehicle under test. Additionally, the targets are only as wide as a normal vehicle--and if that weren't enough, the tests specify the use a combination of radar absorbing material and corner cube reflector to create what is essentially a point target.
