BMW and Tesla both want to create new in-vehicle technologies that can be controlled using smartwatches, with unique features available to auto buyers. The BMW i3 would allow drivers to essentially park a vehicle using a smartwatch, using a mobile app paired with the Remote Valet Parking Assistant feature in the BMW. The app is able to guide vehicles into a parking spot on its own.
The BMW Remote Valet Parking Assistant uses active laser sensors that scan the immediate vicinity to verify the vehicle won't accidentally run into anything. However, there is a "possibility of entirely collision-free driving," indicating the system still isn't exactly full-proof.
Tesla's Model S already has built-in self-driving features so vehicles can park themselves, and incorporating these features in a smartwatch could prove extremely valuable.
