I reckon what you are seeing with Tesla's is kind of what Musk is doing with Twitter... Essentially, remove and/or change a bunch of things (people & features)

I reckon what you are seeing with Tesla's is kind of what Musk is doing with Twitter... Essentially, remove and/or change a bunch of things (people & features) then see if it still works in production. Literally the same thing is happening with a range of Tesla's - the Model Y is the more "normal" car because its cheaper thus more popular. Whereas the more expensive Tesla's have the more experimental crap, because people with more money are tolerant of bespoke/weird shit.
