I would guess that Tesla is losing the premium they can put to their prices and that is pushing Tesla value to a transactional value. No more apologists for the build quality or features that are pay now get it next year(every year, next year), if Tesla makes good cars and sell them at good price people will buy and if they don't people won't. If can't do autonomous driving, can no longer sell autonomous driving. No more paying extra to save the planet.
