The company has put off any notion of an Apple-branded autonomous vehicle and is instead working on the underlying technology that allows a car to drive itself. Timothy D. Cook, the company’s chief executive, said in an interview with Bloomberg in June that Apple is “focusing on autonomous systems.” A notable symbol of that retrenchment is a self-driving shuttle service that ferries employees from one Apple building to another. The shuttle, which has never been reported before, will likely be a commercial vehicle from an automaker and Apple will use it to test the autonomous driving technology that it develops.
Part of me thinks Apple is developing autonomous driving tech mostly because they don't want to give up the market to Google, Tesla and Nvidia. As cars head toward full autonomy, passengers will have lots of time to spend watching videos, listening to news/music, and discovering the world around them. Apple doesn't want to be left out of that.
