We know the current bill will cover deliveries after 12/31/21.
We know some previous versions said the later of 1/1/22 or when the bill is signed.
We know the majority of the dissenting voices directed at the EV portion don't impact Tesla. (No $4500 union kicker).
We know there is concern about the cost, which could drive cuts anywhere.
IMO, this bill is a disaster that I hope completely fails. I'm waiting until January just in case it passes, but I'd gladly lose the $8k to see this whole mess go away.
