Audi's Grandsphere concept EV is a self-driving living room on wheels

If Audi's Skysphere concept is a driver's car with an autonomous option, the company's follow-up is the polar opposite. The automaker has introduced a Grandsphere concept electric sedan that uses Level 4 self-driving (full autonomy in limited conditions) to help you avoid driving "whenever possible" -- this is a luxurious living room that just happens to let you take the wheel. Invoke the driverless mode and the Grandsphere will'reduce' the wheel and pedals to make it clear you're supposed to relax. The displays are really projections on wooden surfaces that adapt based on whether or not you're driving -- you can watch media or participate in video conferences. While Audi's familiar MMI controls are available in an upright seating position, you can use eye tracking and gestures to navigate the infotainment system while you're reclining.
