Tesla enables Autosteer, other autonomous tweaks, in its Model S

Tesla today released an over-the-air software upgrade that enables five new autopilot functions for its Model S sedans, including a beta version of Autosteer and Auto Lane Change.

While Autosteer is more akin to an enhanced adaptive cruise control and lane keeping assist than a fully self-driving vehicle; it does automatically maintain distances from other cars around the Model S.

Tesla founder and CEO Elon Musk has said his company will produce a fully autonomous vehicle within three years.
