Imagine parallel parking into a space and knowing exactly how far your bumper is from the vehicle behind you. It's a dream that rear-view cameras and in-dash displays have only marginally delivered on.

So when you turn around in your seat to back up, it will basically look like the back half of your vehicle has been lopped off.
