It's reported that Apple has laid off a number of staff who were working on its project to produce a driverless car, amidst rumours that it is changing direction to concentrate on the underlying technology.The Apple Insider website bases its story on a New York Times article which quotes sources familiar with the company's plans.It says Apple's autonomous vehicle initiative, dubbed internally as Project Titan, is "getting a reboot" in which, instead of designing and producing a full-fledged self-driving car, the company will focus to work on backbone autonomous vehicle technology.The Titan team was at one time said to number more than a thousand, including workers pulled in from other departments and specialists poached from automotive industry heavyweights.Rumours of Project Titan began last year with AppleInsider saying the project was being run out of a top-secret facility in California, but that executives became unhappy with its slow progress last autumn.
