Way back in February 2015, there were murmurs that Apple was working on a car that would "give Tesla a run for its money" after Business Insider spoke to an Apple employee with knowledge of the subject. This, coupled with sightings of cars registered to Apple, clad with sensors/cameras (which were later debunked), got everyone talking about the prospects of an Apple Car, or iCar.

The iCar project is codenamed 'Titan', according to The Wall Street Journal, which originally stated there were "several hundred" Apple employees working on the project.

While reports originally claimed that Apple was working on a self-driving car, more recent reports suggest that Apple may have changed directions on the project and is now working on an autonomous driving platform.

Whatever the end product, Apple is developing something car-related, whether it's an autonomous driving system, an Apple Car or simply an in-car entertainment system - although the company will never admit what. We'll let you read all the below evidence and decide for yourselves.
