There are also logistical problems to selling electric cars to the poor. You already see well-used hybrid cars, on occasion in the ghetto, where some astute buyer did the math and realized that even a ten-year-old Prius was a good buy and good on gas. For the most part, though, you see a lot of gas hogs in the poor neighborhoods - where we live, it is large SUVs and pickups.
But electrics require a charging station, and charging stations are not cheap and the price is the same for the rich as it is for the poor. The rich guy with his $100,000 Tesla Model S can afford to hire an electrician and install a 220V sub-panel in his garage complete with Tesla charging station. The poor cannot. And unlike a used Prius, there are no used charging stations (or damn few of them) available to the poor - and there is still the labor to install them - assuming their electrical service is sufficient for the load (when I was poor, I lived in a house with 60 Amp service, I kid you not! No, we did not have air conditioning or a heat pump or even an electric dryer!).
Either these things will have to charge from a 110V socket, or the government will have to subsidize the installation of charging stations on streets across the country. Maybe some free-market entrepreneur will have to install them, along with a card-reader to charge customers for their juice. Oh, right, a lot of the poor don't have credit cards and pay cash for gas at the convenience store. How will that work for charging stations?
It gets me to thinking, how will that work for convenience stores? Sure, some will still exist in the inner city. But the vast majority make their money from coffee, donuts, beer, and lottery tickets that people buy when they stop off for gas. The move to electric vehicles will be a game-changer. Or will it have the opposite effect? If people have to sit for an hour to "rapid-charge" their electric car, maybe they will sit down and eat lunch or buy even more coffee and donuts or whatever. It is an interesting thought.
Whatever the outcome, I don't see electric cars being a value proposition to the poor and even the lower-middle-class, unless gas prices skyrocket to the point where going electric is the only realistic option. And if the previous gas crises of the last 45 years are any indication, it seems people will cling to their gas guzzlers as long as possible before they give up and buy a smaller car. And a smaller gas-powered car may be more of a immediate value-proposition to a poor person than a used electric car.
We'll see. It is interesting to think about.
