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.

Individual tax credits/deductions shouldn't have income limits / phaseout at all. We get the progressive taxation on the front end, with marginal tax brackets.
