Tesla makes the exact same car that Apple would have made (simple sleek style, proprietary port, proprietary UI etc), so we already have the Apple car.
Apple has the cash, just buy Tesla, fire Elon and make it so only the iPhone can be the phone key for the car; and voila, the Tesla Model 3 Performance becomes the Apple iCar 3 Pro Max.
you would need to buy the iPad separately and could use the air Dash if you are not willing to fork over the cash, and then you unlock it with your face and wave frantically to get the operation.
