For years, Google and a number of other companies have been frank about their self-driving car efforts. Apple has yet to reveal whether rumors of an iCar are for real, but new evidence suggests it might indeed be in the works.

Documents recently obtained by The Guardian reveal that Apple's legal team met with the California Department of Motor Vehicles last month to review the state's self-driving car regulations, the newspaper reported on Friday. Apple's Senior Legal Counsel Mike Maletic reportedly had an hour-long meeting on Aug. 17 with self-driving car experts at the DMV, including Deputy Directors Bernard Soriano and Brian Soublet and Chief of Strategic Planning Stephanie Dougherty.

Apple did not immediately respond to a request for comment. The California DMV confirmed to The Guardian that the meeting did indeed take place, but did not go into detail about what was discussed.

Rumors about Apple's autonomous vehicle ambitions date back to February when Reuters and The Wall Street Journal reported that Cupertino has "several hundred" employees working on an electric car, known internally as Titan. The rumors hearted up this summer when word spread that Apple hired Doug Betts, former head of global quality at Fiat Chrysler Automobiles.

The Guardian reckons that Apple's meeting with the DMV suggests "the technology giant is close to unveiling an autonomous automobile," but we'll just have to wait and see what happens. Some reports say an Apple car could be five years out, but last month The Guardian also reported that Apple was investigating the use of the GoMentum Station near San Francisco to test its technology. GoMentum is a former Naval Weapons Station also being used by Honda to test its self-driving vehicles. 

We should also remember that Apple, like most tech companies, often experiments with technologies it never brings to market.
