I apologize if I'm coming off snarky, but it's because I'm plugged in to plenty of people who would know such a thing. It's not a "conspiracy theory" - but I've got a deep allergy to BS. And I don't mean this to sound arrogant - it's not that at all - but there's nothing a Tesla rep would know more about this than you or I do. If some memo came out or whatever to the reps, it'd be posted on electrek so fast Starlink couldn't even handle it.
And if my folks that talk to the Assembly on an almost daily basis haven't heard a peep about such a monumental shift in policy, I doubt a random sales rep would know any more than they do.
The "but the salesman said ..." thing has gone on since Ugg the Caveman.... has nothing to do with EVs or you personally, of course! Just that rumors spread faster than wildfire, and I really don't want to spend the next 6 months cleaning up behind rumors that never actually happen.
All that said -- if something crazy happens and funding gets pulled, believe me, I'm more than good for my apology and eating some crow. I've developed a taste for crow - preferably with a little ketchup on top. ;-)
