Tesla has consistently been adding software to its in-car touchscreen infotainment displays — including sometimes things that probably leave a lot of people scratching their heads. During a special Q&A today at annual gaming event E3 in LA, Tesla CEO Elon Musk revealed that Tesla’s in-car display will support YouTube someday soon.

This isn’t the first time the Tesla CEO has suggested YouTube might one day have a home in the company’s cars: In response to a fan’s question on Twitter last August he noted that version 10 of the company’s in-car software would provide support for third-party video streaming. The company debuted its Software Version 9.0 last year.

Musk specifically said YouTube would be coming to cars during the E3 event today, at which he revealed that Bethesda’s Fallout 3 would be coming to the infotainment displays, and unveiled a demo video of Android game Beach Buggy Racer running on a display in a Tesla Model 3.

On a recent podcast, the Tesla CEO also said the company would consider opening the platform more broadly to third-party developers for both apps and games. The company has done a lot on its own to add software “Easter Eggs” to the dash display, but turning it into a true platform is a much more ambitious vision.

On its face, adding to a car attention-heavy apps like streaming video services definitely seems counterintuitive, but to be fair to Tesla, a large number of drivers today use their phones for in-car navigation and those can also all technically display YouTube at any time. It does seem like a case of Musk’s mind racing ahead to a day when his cars are fully autonomous, something he recently reiterated he expects to happen within the next couple of years.
