Tesla made a blandly designed electric sedan a status symbol, which is no small accomplishment, and the company's fight against the system of state-regulated, independent auto dealerships in the United States--which indisputably harm American consumers--is commendable.
However, in light of Tesla's dependence on various forms of government subsidy, Musk's attitude toward the risks that his company's products and production methods generate is perplexing. If a company relies on the public sector to stay in business, the company has to be squeaky clean, so to speak. It's impossible for a company to achieve squeaky cleanliness when it rejects the engineering and production process know-how of the major manufacturers in its sector in favor of making and selling a car in beta test mode and then relying on hacks and software updates to fix it.
On balance, I am not a fan.
