Make the screen function more like a real window.
A screensaver showing a beautiful scene and behaves like a real window to that scene would: when you move or turn your head the displayed scene will change to reflect your point of view of the scene as you would see it through a real window. The built-in camera can be used to track your movements.
So you can see as a tourist where you might want to get off the bus and explore.
Have the windows (transparent LCD screens) show interesting information on places as they pass by or about to, so you can decide to get off when you see something interesting.
