Rumours of the possible existence of an Apple car have been making rounds for ages. Over the years, various executives have come and gone, and several carmakers have been tied to the project. And now, there's further proof that Apple is developing systems for a car thanks to new filings from the California Department of Motor Vehicles (DMV). In order to develop its vision for a car of the future, Apple has been testing its automotive driving tech on the streets of California. As part of the testing of these systems, the firm is required to log all miles covered by self-driving cars with the State of California. The firm does this alongside companies like Waymo and Cruise, which are also developing self-driving cars.
