Hmm I think if a vehicle is moving even 5 mph it would be easily picked up by radar, and its only truly stationary things that are a radar "blind spot". I suspect its a vision or fusion problem--as the article points out, the lighting wasn't great. Why doesn't the car use ultrasound for AEB? Perhaps risk of false positives coupled with the fact that its range is so short it would only have time for limited braking anyway?
