Which should not be that surprising. Teslas were priced as premium vehicles initially, and then dropped as competitors appeared and to take advantage of tax credits. Teslas also benefit dramatically from owning a garage and adding a charger to it, which mostly homeowners can do.
A homeowner buying an expensive car is very likely older and richer.
Teslas aren't cool anymore, they are what your parents and your Uber driver has.
