Tesla CEO Elon Musk is telling customers that the company's first version of its "autopilot" feature will be flashed into their electric cars on Thursday.

Musk sent out a tweet Sunday saying that the Version 7 software will include Autopilot.

While details of its capabilities are yet to be released, it is expected that Autopilot will, at the very least, be able to hold the car in its lane on a freeway. The company is also working on a feature that will allow the car to park itself in a garage.

Autopilot is a step toward self-driving cars. Musk told shareholders in June that he thinks fully self-driving versions of the Model S could arrive in as little as three years.
