In the grand scheme of things, that's irrelevant for Tesla. Right now it's good for PR, and it's good that it makes at least as much money as the others. But unlike Tesla, Porsche will never make a mass-market play. Tesla will - at least in the sense that Apple is making a mass-market play in the smartphone market. Tesla may never become the biggest "car company" in the world, although there's a pretty big chance it will become (if it isn't already) the biggest "electric car company" in the world. Either way, it will be a very important and popular car company, that will get big enough to be able to drag the whole industry after it, and set the standards for the industry.
