That would be the boat of early adopter people who are willing to pay top dollar for a car that, apart from Superchargers and a large screen is not on par with BMW and the like in things that actually matter to luxury car buyers, like build quality and comfort and handling? Actually, on build quality Tesla doesn't really compete with cars that are half the price.

Does not seem to be a huge boat to me. Not that BMW couldn't screw it up before then, but they will need to try really hard to screw up.
