The elephant in the room, though, is that we're being eventually forced into it - whether we love it, don't mind or hate it.
If the situation were that EVs will be freely available for those who want them and ICE cars will be equally available for those who want them, there wouldn't be any need for strife or disagreement.
It would be like people furiously arguing as to whether tea or coffee are better, and which one everybody 'should' drink, when every cafe sells both and will do indefinitely.
If you take something like smartphones, the government has never hinted at making them compulsory; but the vast majority of people now have them, because they saw all that they could bring to their lives and actively chose to buy one - albeit you can get used ones for £50 or so, rather than having to spend thousands.
Nobody has ever banned fax machines, video cassettes or film cameras, but how many people now still have and use them? As soon as people saw that there were far better, much more desirable alternatives available, they actively chose to dump them in favour of newer, superior tech.
I think, if EVs genuinely are as revolutionary and amazing as proponents and governments claim they are, they wouldn't need to do anything to promote them - as word would spread, people would discover and try them for themselves and be eager to make the jump to them without any bans ever being necessary. Indeed, plenty of people have made the jump and say they would never go back; but they don't and can't decide for everybody. Consumer choice and free markets are very important things in a democracy.
