iCar? Apple said to be interested in auto testing ground

1SAN FRANCISCO -- Adding fuel to rumours that Apple is working on designs for a car, local officials say engineers for the giant tech company recently made inquiries about a former navy base that's been converted into a testing ground for self-driving cars and other cutting-edge vehicles.
2An official with the Contra Costa Transportation Authority says the giant tech company hasn't said what kind of testing it hopes to conduct at the decommissioned base in Concord, east of San Francisco.
3The agency is promoting the base and its 20 miles of closed roads as an ideal test facility for new automotive technology.
4Apple declined comment Friday.
5Despite recurring reports that Apple is interested in building its own car, the tech giant has never confirmed any plans.
