And local governments get sales tax on each car sold as well.. Figure 7% average sales tax (most cars are sold in CA - 7.5%, NY - 4.5%, MA & TX - 6.25%), and an average price of $80k; 11,500 Model Ss would equate to about $65M into state coffers for Q2 alone. Of course, many are sold overseas so discount that number a bit, but either way, states are probably happy.
