Las Vegas (CNN) - Imagine a future in which icons flash on your car windshield, hologram style, as your car approaches restaurants, stores, historic landmarks or the homes of friends.
Simply point your hand at them, and the icons open to show real-time information: when that bridge over there was built, what band is playing at that nightclub on the left, whether that new café up the street has any tables available. Wave your hand again, and you've made a restaurant reservation.
Mercedes-Benz showed off this vision of the future of driving - complete with augmented-reality and gesture-controlled features - this week at the International Consumer Electronics Show.
