Tesla is the automotive equivalent of Apple. Cheaper alternatives will come along (such as the Chevy Bolt).
Except Tesla probably have a significantly higher BOM than most car makers, due to low volume and new tech. Apple have no such excuse, using no more advanced tech than anyone else, and having massive volume to boot, yet still charging a massive premium.
A better analogy would be Ford charging Tesla prices for their everyday cars, and people still buying them.
