I think you may be more likely to see Augmented Reality in conjunction with a heads up display with Apple CarPlay, where linked with GPS, the Turn-by-Turn directions would appear on the windshield, along with information on businesses and attractions coming up ahead, such as the type of services available, food types available, relative costs, ratings, etc. in a graphic mode, but not too distracting. It could become much more effective with a self-driving car. Where a passenger could ask for information on what restaurants are coming up ahead in the next block, etc.
Let's hope it wouldn't be used for spotting and running over Pokeman Go characters! Some drivers might not be able to tell the difference between a character and a pedestrian or bicyclist. Oops. Sorry about that.
It will have a lot of really great uses and some totally bone headed uses.
