That's *probably* not true. All the car makers were given various "rebates" to offer for electric and hybrid vehicles, but it was limited to a certain number of cars produced, and scaled to the type of alternative fuel used. The more efficient, and less pollution, the higher the rebate. Companies like Toyota and Honda, who were early adopters, burned through their Hybrid credits quickly, but I think they still have some EV credits left on new all-EV cars. Tesla is probably still getting their credits because they are newer, sell fewer cars, and are all EVs that have higher rebates. But they will eventually burn through their credits, as well.
