You say that like they bought something off the shelf which just worked the first time they used it. They did not - it was a collaboration and Tesla spent a lot of money and time to get it to work.

I'm not gonna link the articles, but there are photos of the mountains of defective parts and plenty of people complaining about how terrible the first cars produced that way were. Tesla persevered and now other car manufacturers are trying to duplicate their results.
