Tesla’s new self-driving software will be released widely Thursday, but one Tesla driver with early access already posted footage of the autopilot to YouTube. He cruises along a highway — hands completely off the wheel — as the Model S holds its lane without trouble. A few times the driver flicks a turn signal to activate a lane change, which the car then executes on its own. The new feature in this version 7 software that we don’t see is automated parallel parking.

By automating highway driving, Tesla is already delivering a feature that many major automakers are promising to deliver several years down the road. Toyota and Volvo recently said they will commercialize self-driving technology for highway driving in 2020. GM is promising a similar feature on one of its Cadillacs next year.

While ahead of traditional automakers, Tesla seems significantly behind Google on the software needed for fully self-driving vehicles. Google has 48 self-driving vehicles testing in Mountain View, Calif. and Austin. The cars are not limited to the easier task of highway driving, and are covering more than 10,000 miles a week in autonomous mode.

Tesla will be sharing details about its new software Wednesday afternoon.
