Like many things, it's a question of definitions. There are already cars on the road operating commercial autonomous services. It's new and immmature, but in a very real sense "self-driving" is already here. L5 or offroad might still be decades out from initial introduction.
Toyota already makes cars that work really well and the company as a whole is undervalued (less than 1/3 of what TSLA is valued at). The point is for Apple to get into a huge market and make a ton of money with a best-in-class product. And no, self-driving is not already here.
