They did with model s and x leases back in like 2017 they sent out to lease holders if they wanted the option to buy it out and you could buy out those leases right up to late last year when they changed it cause of the marketTesla will never change the verbiage in existing lease contracts to allow for buyouts, I would literally bet my life on it. Kind of comical even debating it. Now could they change the paradigm in the future? Maybe... but even then I don't see how that would be a needle mover for them given the volume that they are pushing.
Companies can have done these changes on and off before nothing new, contracts and verbiage can change if both parties agree
Honda and toyota and almost any car company would let u buy out leases for decades and even those 2 put a hold to that last year cause of the used car market
When the market settles or goes back it will probably change again and send out emails and crap hey u wanna buy out ur lease blah blah
