The achievement of making a big swept up "yankee supertank" is in making more profit which finances the next, progressively more affordable, generation of EV. This is a well published strategy of Tesla. The first Tesla was a completely un-necessary but highly desirable car, that barely anyone could afford. As new models have been released they have been progressively more practical and more affordable.
The Model 3 barely (if at all) qualifies as a supertank.
