Yes. But you can also get into a project and realize a commercially viable output is going to take too long and cost too much. (And pretty much every auto manufacturer already has assistive driving systems at some level.)
I highly doubt the problem was, can Apple build a car? They have enough money that they could probably hire the people to do just about anything they wanted to try.
Not really sure how you simplify making a car enough to make it worth getting into the market at all in the first place.
But actually entering the market and getting Apple like margins and volumes... Very doubtful. Cars are significantly more expensive than even the VR headset or top of the line computers.
