I think the idea is NOT to serve entertainment to the driver, but to build something to show/manage:
- video feed from rear camera while parking/etc
- proximity sensor warning display, also used while parking for instance
- GPS navigation
I believe the entertainment aspect (as far as the driver goes) is to control the video display at the back-seat terminals that the children are watching (like turning it off once they fall asleep). Not very different from selecting radio stations.
The units at the back-seat will probably have a stronger entertainment aspect.
On a personal note, I used a car with proximity sensors last week, found them wonderful. There was a large warning at the display about "look to confirm safety" (or words to this effect).
I thought it was silly until I thought that many will just stop looking anywhere else. Like folks that drive into a river because the GPS told them so.
