> how do you back-up safely without a screen to show you what’s behind you? The older style of parking sensors based on ultrasonic sensors which use beeps and a diagram of the car to indicate what’s behind you and how far away is superior to a camera and doesn’t require a screen (could be done with a few LEDs if necessary) If you have to look at a camera in front of you to back up, you can’t see everything else in the field of vision behind you that’s not covered by the camera. Furthermore screens have much worse resolution and dynamic range than your eyes.
