Give that to the kids and it will entertain them for hours. By hours I mean fifteen minutes.

Several competitors starting to pop-up here. One downside on all of them currently is, you need to connect to a wifi network generated by the camera. They have mini-routers built in because of the speed required to even come close to streaming real-time video.

Brand is pearl. Uses a cam on a license plate frame. Never seen it first hand though.

I just wish I could have my rear-view camera on while I was driving forward.

You can with the appropriate device on certain cars. I retrofit a newer headunit into my older truck and also have the added benefit of turning the backup cam on whenever I want.

It would be nice for a lot of reasons but I think over all the net damage from the distraction would be more than the damage saved by people realizing they forgot to pin the trailer coupler and similar stuff. You don't have many reasons to see that field of view at speed since pretty much every reverse camera basically points down.

Rear view mirrors are useful while going forward. But, it's fairly easy to block that line of sight in a full car, thus making the rear view camera a useful backup.
