I'm not really sure what you're getting at. Having to move far out and getting several roommates just to swing the payments on your Model S is not exactly my idea of comfortably affording the car.
I wouldn't buy a Tesla on $100k in North Dakota either. Maybe, if I felt like blowing through money, I'd get a BMW 3 series or Audi A4, both of which are still considerably cheaper than a Model S.
I'm not disagreeing with you re: the Tesla S is way out of reach of someone "only" making $100k.
I was just pointing out that besides housing (especially owning) the cost of almost everything in CA is the same if you move somewhere where the cost of living is lower yet the salaries elsewhere are significantly less. So there is an opportunity to save a lot of money if you are willing to compromise somewhat on your living conditions.
I suppose it depends on whether you think it's important to own your home and/or you mind having roommates. When I first moved to CA I had severe sticker shock re: the rents so I rented a room in nice houses with other young professionals for the first 5 or so years I lived here.
