While Apple revolutionized some industries in the past, I wonder if manufacturing cars makes any sense for them. Under Steve Jobs, Apple has completely changed computers, the music and entertainment industries, cell phones and mobile devices. They did all this to sell hardware.

I don't see how they can revolutionize the car business anymore than Google or any of the other large companies doing autonomous cars. They're going to have to bring something to the table other than a car. All of the large car companies have autonomous vehicle research programs. They can spin out a product, as they've done when Toyota's Prius became a commercial hit. On the lower end of the scale, there are cars coming from China, possibly India and other nations which are due to hit the US soon. Getting into the auto market against the high end Mercedes, Audis, BMWs, and Italian cars would be a tough market. They would also be competing against well established and loved brands. Not sure what part of the market they would fit in or even target.
