Well, it can detect things lying on the ground, but not completely. If the object is low, it might detect it at the first range (3-5ft) but as you get closer the object gets too far below the sensor's field of vision (or hearing I guess) and will then stop warning you about it. So if Jr drops his bike right behind the car, your first warning is the crunch.

Two climate control systems, one inside and the other at the tailpipe.
