My understanding is that the proposed tax credit is intended for point-of-sale price adjustment. This means that all Models 3 and Y in the new year may be officially priced 8k lower including the tax credit. If Tesla keep 49,990 price and then apply 8,000 tax credit, then at 41,990 the demand may cross into unhealthy territory frankly. So they are now at 57,990 which will be 49,990 after they apply the tax credit. It is reasonable to expect that MANY people who ordered at 53,990 and 54,990 and who have delivery date in 2021 will delay until 2022 to get the car at 45,990 or 46,990 final price. If Tesla offer them to buy the cars at 49,990 now, they may take delivery now keeping sales moving.
