And so? Tesla got credits and others had to pay Tesla to get some credits. Even for a kind of fake battery swap demo, they got credits.
If your beef is with the government, then vote them out, contribute to a PAC, start a PAC, or run for office yourself.
If your beef is with Tesla, then explain why a business shouldn't take advantage of a law as written.
AND note the following:
• The law was changed and Tesla no longer receives credits for battery swapping capability.
• Credits are not cash. The government does not give money to Tesla.
• Other OEMS, like Fiat-Chrysler, give money to Tesla because by law they need those credits since by law they have to produce a certain percentage of vehicles that pollute less or not at all. If FCA, GM, Ford, BMW, etc. had started producing hybrids and battery-electric vehicles back in 2012, like Tesla did, they wouldn't need to buy credits from another company and Tesla's credits would be worthless.
Instead, the automotive OEMs decided it would be cheaper and better for them to continue to make polluting vehicles and buy the necessary credits (both the US and EU have such systems) from other companies rather than spend the time and money to design and build BEVs or other vehicles that polluted less.
Matter of fact, some OEMs decided to cheat the make vehicles that behaved differently during emissions tests than they did in the real world. These OEMs, like VW, Audi, Mercedes, Chrysler and others, literally decided to pollute the air you and I and our children breathe, and then to lie about it, rather than make better vehicles that didn't harm our environment as much.
You're picking on the wrong boogeyman. Tesla's not the problem here. Go ask GM why they stopped making the EV1 just after they got the automotive pollution laws in California changed, and then destroyed just about every EV1 they had produced. Go ask Ford why it's taken until the third decade of the 21st century to make an EV that people would actually want to buy. Go ask VW why they intentionally made vehicles that polluted less when being tested than when being driven, and why they intentionally illegally turn off pollution controls at certain times while driving (Germany just ruled on this one, btw).
And again, if you want to change the laws so vehicles can legally pollute more or have no monetary requirement to make vehicles that pollute less, do something about those laws, but frankly it's misguided to rail against companies like Tesla that are both following the law and producing vehicles that harm our environment less.
