In early January, Tesla released the standard range. It's a very competitive offering for those who have shorter commutes. I believe it started to receive a lot of orders. But then early February, the New Green Act bill was announced. Everyone buying SR are doing it because it's a cheaper option and a great value. So now if they delay they could now get an even better value and save almost 20% by delaying their order so most people delayed. Tesla then decides to lower the price to try and get people to keep their orders but I don't think many were persuaded. Now, Tesla has many SR in stock and demand is down across the board so they decide to remove ordering for it. Why else would they have built so many of them that they now have in inventory? Also, Tesla probably didn't have good margins on them and they canabolized the LR sales too.
