In the areas that Apple competes there are a handful of serious competitors and they deliberately place themselves in markets where they know they can offer a superior experience. In the automative industry there are dozens of competitors. And most of them over at least some cars that are higher in quality than Tesla. And of course none of them have the problem of electric cars namely range and worrying about recharge locations. Which is a concern for the mainstream masses.
For me Tesla is more like the Windows Phone. A great product but with quite a lot of uncertainty around it's longterm future.
