To increase rear visibility, modern GM vehicles with a rear wiper (SUVs and CUVs) will automatically swipe the rear wiper if the front wipers were on and the vehicle is put into reverse. It will even do this if the wipers were on in the previous ignition cycle (as in, it was/is raining, you're returning to a parked vehicle, and reversing out of a parking spot).
First gen Chevrolet Colorado and GMC Canyon had tailgate cables with multiple positions. Unhooking the cable and moving to the alternate position would hold the tailgate at the perfect angle for loading a 4x8 sheet level between the tailgate and wheelhouses.
Many new vehicles use the steering angle sensor and lateral/longitudinal/yaw sensors used by stability control systems to determine if you're driving in a parking lot. If you are, it won't auto-stop the engine if the vehicle has start/stop.
The TPMS system on some new vehicles will automatically recognize air being added to the tire and honk when the specific pressure is reached. No need for a tire gauge.
