BMW’s new automated i3 uses these sensors to prevent collisions when out on the road and the four laser assistants are the centrepieces of its new fully automated parking service. The Remote Valet Parking Assistant, which is activated by smartwatch, allows a car to be parked in a multi-storey car park by using the i3 laser scanners to map the structure of the car park as well as the position of other cars, even those parked incorrectly, and park itself.
