The revamped Model S and Model X still have big central touchscreens (now in a landscape orientation, rather than the previous portrait-oriented screen), but Tesla went even further by eliminating the turn-signal and gear-selector stalks. Tesla CEO Elon Musk said the car will simply "guess" which way the driver wants to go based on sensor data and navigation maps. Tesla is expected to include backup controls as well, leaving drivers to use the touchscreen for selecting drive, and steering-wheel controls for turn signals.
