Because there are lots of things the Tesla does that nothing else does in the same way, or the overall package of other vehicles (price, features, functionality, intangibles, whatever) doesn't match for that particular buyer. I'm constantly amazed that otherwise intelligent people latch on to a single "factual" reason that proves they must be correct about a matter of opinion, particularly when their experience set is often objectively less relevant. To wit: presumably the parent has owned numerous other cars in addition to the Teslas.
