Recently there was a fatal crash of a driver using the Tesla Model S’s autopilot feature. This brought discussions of driver assist technologies to the forefront. There are a number of companies working on developing self driving cars including Tesla, Google, Apple, and BMW.
Tesla’s autopilot uses Autosteer to keep the car in the current lane and Traffic-Aware Cruise Control to maintain the car’s speed. On a highway, the car will virtually drive itself. Tesla’s autopilot requires that the driver’s hands stay on the wheel while driving to enforce driver engagement.
