I've said this before = and I'll say it again - TESLA has survived the last 5 years by selling cars to technology people and fanboys who want the snake oil they sell.
I agreed with teh rest of your post but this section needs clarifying: drawing a parallel between Tesla and snake oil sales tells me either you don't understand what snake oil salesmen were all about, or you're just reaching to take a swipe at Tesla out of anger. If it's the latter, that's your prerogative. If it's the former, it should be clarified...do you think Tesla is a fraud, and are willfully deceiving the public? If so please clarify?
Tesla started out as a nice new electric car company. It has morphed into the giant it is today with tentacles reaching in all directions largely because capital markets are giving them an incredible currency (stock issued from treasury) that they can use to provide growth. Those same capital markets indirectly gave Tesla their start, when the financial crisis resulted in several major manufacturers being forced to cut back and sell off major assets that would be unaffordable for most startup car companies. Tesla bought them up in a firesale and were able to start out with little to no debts...which is what usually crushes a new car company.
Comparing the company to a snake oil salesman - a fake doctor who knowingly sold bullshit in a jar as the cure for all illnesses - because your wife's Model X broke a few times...that's a bit strong.
