When you're a kid stuck in the backseat of your parents' car, life is pretty boring. There's only so much you can do staring out the window. But Toyota's new Windows to the World concept would certainly change that.
The idea is that the back windows would be made of a transparent touchscreen glass, allowing backseat riders to get information about what they're seeing, pinch to zoom in on things in the distance, and things of that nature. You can also imagine some clever games being made that would take advantage of the constantly moving background.
Between this and in-car entertainment systems, I was obviously born in the wrong decade for childhood roadtrips.
