According to Tesla boss Elon Musk, a software update is coming that will enable the Tesla Model S to steer itself on the highway and parallel park autonomously. Announcing the plan on Twitter, Musk said that dealing with low-contrast lane markings has been the final hurdle to getting the feature working.

Highway Autosteer makes the Model S capable of NHTSA's level two automation, still a far cry from a car being able to remotely drive itself from the beginning to end of a destination. While Tesla has made many announcements recently about self-driving features for the Model S that will be unlocked via the version 7 firmware, it remains unclear exactly how such cars will be legal on US roads outside of California (which has issued self-driving cars with permits).

This is no doubt an exciting update for Tesla owners. However, we'd be remiss if we didn't point out that plenty of other cars already come with adaptive cruise control and lane centering—the Audi RS7 we drove last month is one such example. And self-parking cars predate the smartphone age, with Toyota being the first to market in 2003 with self-parking Priuses (in Japan). Still, welcome to the club, Tesla.
