Regulatory approvals received, so Autopilot rolling out to all countries! (Excluding Japan, which is still under review) — Elon Musk (@elonmusk) October 23, 2015

Autopilot 1.01 coming soon: curve speed adaption, controller smoothness, better lane holding on poor roads, improved fleet learning! — Elon Musk (@elonmusk) October 23, 2015

Tesla's semi-autonomous driving feature, Autosteer is still in the beta stage. Drivers are encouraged to keep their hands on the wheel while the car navigates the road and traffic. If the system gets confused or detects a section of road it can't navigate it will inform the driver to take over driving duties.

The improved fleet learning shipping with the Autopilot update should help solve some of the issues the system has with roads with faded markers. As Model S drivers navigate over a problem portion of road, they are mapping it and their lane position.
