> They completely negate any environmental benefit to buying a Tesla, since the purchase just lets some other manufacturer sell one more dirty SUV. That isn't how that works. If each carmaker is required to sell 20% EVs (or whatever) and then Tesla sells 100% EVs and Chrysler sells 0%, the overall average is still at least 20% and you're still buying an EV. It's not any less "buying an EV" than it would be to buy a Chrysler EV which also allows Chrysler to sell more ICE SUVs. Moreover, the number is the lower limit -- if Tesla sells 100% EVs and Chrysler sells 0% and they each sell the same number of vehicles, you'd then have 50% EVs even if the law only required 20%.
