I don't know what is necessarily novel in this. For example, I remember (but can't find) a feature for a high end car that showed IR camera display to highlight unseen deer on the road.. Anyway, I think this is a good feature for intermediate automated cars. There is a problem with keeping people interested enough to be ready to take over if there is a situation that the computer lacks the confidence to deal with. One application might be to turn the display into a game field. When there is traffic, you could be able to interact with the other cars on the road. When there isn't there could be simulations. That way, you are always looking forward and at least somewhat engaged. As safety confidence drops, the system can highlight the area where the problem is developing, giving a subtle hint to get ready. For later iterations, the controls could become more "game controller" like where the driver is choosing between different scenarios and the system figures out how to do it.
