Not to mention there are severe income limits on the rebate

Right, set too low (imho). And not a graduated phase out either. And the market for these cars are going to be people typically past the income limit. My instinct tells me that people below the income limit ($75K/$150K) probably aren't really in the market for an EV. They are probably just trying to keep their regular gas vehicle running. An EV is almost a second/third car for a lot of people, commuters trying to offset their gasoline costs.
