I was thinking about that Volvo video where the car smacked into the rear of the transport trailer and was wondering if the system didn't 'pick-up' enough 'reflection' from the rear of the trailer, ie. a typical car rear-end has more surface area with fewer 'gaps' to reflect ultrasonic energy from than the relatively 'open' area at the lower-rear of a transport trailer.
