Apple's chief executive has confirmed it is developing a self-driving car system.
But Tim Cook indicated that it is too soon to say whether it would license the tech to other carmakers or try to build its own vehicles.
His interview with the Bloomberg news agency yielded his most detailed comments about the project to date.
Until now, Apple had avoided publicly discussing its plans, although it had confirmed the scheme in US filings.
There had also been leaked details of a change in leadership of the car team, with veteran hardware specialist Bob Mansfield reportedly put in charge last year, as well as images of test vehicles being published on rumour sites.
