I think at this point we also need to massively raise the gas tax, pay it back as a universal dividend to avoid right-wing revolution. And simultaneously, we need to build a bunch of transit so people trying to win the gas-tax-dividend arbitrage have a valid strategy. Make the demand, make the supply.

Our political situation doesn't allow for that, but I don't really see the choice? Trying to electrify all the cars is perhaps easier on the American psyche, but much less efficient, and will not help with all the non-global-warming major externalities we need to fix nearly as urgently.
