I have both a full EV that can be charged on any standard power plug and a classic gas car. I barely ever use the gas, and only use the EV because of how much cheaper it is. I would’ve expected everyone to do the same, but maybe as you said gas is not expensive enough for most people so they don’t care.
Yes, I think EVs in general (and especially hybrids) are a way to justify not investing in alternative modes of transportation for cities.
As for users you feel good about being “clean”, but in reality you are still polluting 10x as much as with public transportation.
