I think it was mentioned briefly but having a camera built in servo motors be able to adjust with the rear view mirrors would be beneficial. Say on the driveway and as you move the mirror L to R to get a better sense of what not only behind you but perhaps below your bumper. Make it a smart rear view mirror.
This would be good for police to if sensors were attached to the mirror to alert you to someone coming up or a kids ball just wedged under your car. A lot of positives with this. Your sensory awareness would definitely extend outside of your vehicle.

Finally coming into production in the coming years. Glad It's happening
