It would be great if you could add the ability to look left and right using mouse movement. Similar as to a FPS games. I think it would a more gamae like feel.
You would then be easily able to see people aproaching watch them ride by etc.
The other advantage then would be the ability to link VR based glasses that allow mouse tracking giving a full VR experience… (it would get hot with them on but my inner geek would love it)
