Parking lots are poorly designed in that they literally encourage cars to back into each other.
Geometric parking is the way to go.
I drive a Tacoma Double cab Long bed. It is almost impossible to pull into a parking space going forward. Therefore, I typically back in. With the camera you can safely get within a few inches of the vehicle behind it.
Geometric parking makes much more sense. The town I formerly lived in had it in their downtown main street instead of parallel parking.
