Tesla Motors is launching its new autopilot revision, Autopilot HW2. The product is a semi-autonomous system. While all of the company's cars sold since October 2016 have included the range of radar and ultrasonic sensors, 8 cameras and upgraded on-board computer, the full capabilities of the system have yet to be utilised. The company is launching its autopilot software that will take advantage of the new hardware at the 2017 North American International Auto Show. The update will affect 1,000 cars, with the rest running in 'shadow mode,' collecting data about what the car's AI would do if autopilot were active.
