Last month here EVs made up 64.1% of cars sold. 27.6% were hybrids and only 4.3% powered by gasoline and 4.1% ran on diesel. The incentives are very skewed towards EVs and electricity is relatively cheap (around $0.15 / kWh while fossile fuels are very expensive (around $6.50 - $8 / gallon depending on loction) so the maths are quite different compared to the US. And pretty much 100% of our electricity supply comes from renewables in the first place.
Where is "here"?
Norway, home of heavily taxed cars and gas.
EVs are excempt from VAT (normally 25%), all car taxes (of which there is a shitload, generally calculated off weight and emission numbers), pay reduced yearly road tax, pay nothing or have a significant discount on toll roads and reduced parking fees on public space in cities. 14-15% of all personal cars are EVs so it takes a lot of time to replace the existing stock.
Im not really into car prices but to give you an idea a new Honda CR-V costs roughly 10-15k USD more than a new Tesla Model 3 AWD Long Range here so its quite different from most other places.
So based on this single data point (i.e what is happening in Norway) you can get a significant change provided strong incentives, but I guess if the US introduced norwegian car and gas taxes there would be a civil war or worse so it's starting from very different departure points. There are currently discussions on scaling back the incentives somewhat as the government looses significant revenue, cars being a cash cow for the government since the dawn of time. Currently the main topic is VAT on purchase price over a certain point. If introduced it will affect "luxury" cars like the electric Porsche. Teslas S and X models, the Audi E-tron but barely anything else afaik.
So due to the history adaption has been quicker here than most other places can expect. If you can live with the limitations of an EV (range, charging etc) its generally a pretty simple choice measured in money as the cars tend to be cheaper than a similar ICE car, especially on the higher end of the scale and much cheaper to operate due to high gas prices etc.
This is also why hybrids are popular, due to the somewhat optimistic official numbers for emission (CO2 and NOx) compared to real life it becomes a bit of an arbitrage vs the car tax system. You can buy one, get the reduced car tax compared to a pure ICE and if you end up ever charging it and driving it partly electric or not is irrelevant.
