My issue with tax incentives is that they are given without regard to income level of the buyers. I do not believe tax incentives should be given to the companies that produce the cars, only to the public who buys them and then only weighed against income level.
Get the middle class into these electrics, if the rich want them there is no reason the middle class should subsidize their purchase
Be careful with that line of reasoning. Rich people respond to tax incentives more than the middle class in a lot of respects (because they have more economic freedom), and some of the draw for the upper middle class is that the Tesla is a rich person's car/status symbol.
Making the rich move back to MB S-class and Porsche 911s and you take away at least part of the allure for the numerically larger upper-middle class.
Plus, realistically, do you really want to differentially encourage a $75 K/yr household to buy a car that's not economically rational/healthy for them to buy? You want more Teslas on the road via incentives? You have to give the incentives to the people who can afford them...
