Are they just doing object detection, or are they also doing 3d scene reconstruction (visual SLAM)? My bet is on the latter, and the SLAM reconstruction should show them that there's something dangerously close to the car. Of course, vSLAM is notoriously finnicky in corner cases, lighting conditions etc., so it might have just not noticed the plane at all.
