Tesla today is rolling out second-generation Autopilot update to all of its Model S and X vehicles built since October 2016, according to company CEO Elon Musk’s new Twitter post. He says that some cars will require camera pitch angle adjustment by Tesla’s service department. The over-the-air update is available for second-generation Autopilot hardware, which until now have been have been without safety features that are available in many older Tesla cars such as Forward Collision Warning but also adds Autosteer (limited to 45 mph for now) and traffic-aware cruise control (until 75 mph). Newer Tesla’s still will not have Autopilot and semi-autonomous features offered in older models–because the software is still in development for the newer, more advanced hardware.
