Mercedes' Drive Pilot system will accept full legal responsibility for the vehicle when active, making it distinct from other semi-autonomous systems like Tesla's Autopilot. The system can operate at speeds under 40 mph on certain highways and will give drivers a 10-second warning before disengaging. Mercedes hopes to deploy Drive Pilot in the US by the end of 2022. The system's capabilities and limitations are being tested and refined, with the goal of providing a safe and reliable semi-autonomous driving experience.
