Toyota Makes The Backseat Invisible
 

This idea is pretty neat, I just wonder how well it will work with people sitting in the back seat? 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. But this technology promises to turn a vehicle's entire back seat into a giant display showing everything happening behind the vehicle in full scale. 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.
