For most of 2015 we've heard talk of an Apple automotive project of some sort, with rumors ranging from an advanced, high-tech interior system all the way up to a bona fide Apple Car which will probably be on stage in 2019.
Specialist engineers are deployed in the production of this electric car. It will be designed as an autonomous vehicle, with self-driving capabilities.
The project is in operation under the code name Titan. Apple's Titan team is said to number around 600-1800 individuals.
