The lack of competition was itself a reflection of conventional wisdom in those industries, though, which is my point.
Tesla's competitive advantage was a willingness to cut corners. Other companies have been testing, developing production processes, building supply chains. You can bet there won't be a Bloomberg model 3 weekly production tracker for their cars since they'll make what they plan, which will actually happen when they say.
If you measure performance in 0-60 only, and pricing/efficiency in self reported/marketed EPA range (not actual real world range) then Tesla is definitely ahead.
What I meant is that they are selling a car at $38k that outperforms the competition on range, efficiency, safety, space, performance, tech, driving assists; it includes features like the panoramic roof that cost an arm and a leg as optionals on every other car. So clearly they are doing something different in their manufacturing.
Before SpaceX, there was little to no competition in reusable, cost-efficient rockets. Before Tesla, there was little to no competition in attractive, high-end EVs. That's why they're successful. There was, however, a lot of competition in car mass manufacturing. It was arrogant and misguided of Tesla and Musk to ignore industry knowledge in highly competitive areas.
