Tesla's Enhanced Autopilot update has rolled out to all its HW2 vehicles, company chief Elon Musk has announced on Twitter. HW2 is what the automaker calls its second-generation self-driving hardware found in its newer models, including the Model S and X. The Enhanced Autopilot update was designed to bring several autonomous features to the new hardware, such as autosteer, smart summon, autopark and auto lane change. Some of those features were available on the first-gen hardware, but Tesla had to deactivate them for HW2 until they've undergone more testing. Unfortunately, it might still take some time before you can try the reactivated features unless you're one of the 1,000 testers who had early access to them.
