I suppose I'd respond to that like this:
1: As can be seen from elsewhere in this thread, there are still many, many EV doubters. They come in all shapes and sizes varying from pure "petrolheads" for whom the racket from either a monster V8 or an over-stressed 1.2 litre (and all points in between) added to the satisfaction from neatly wrestling with gears and clutches and so on is a primary consideration, through to those who simply can't get into the different refuelling mindset and/or who see upfront cost as showstopping, rather than considering weekly/monthly cost in comparison. Oh, and the eco-doubters.
2: It seems to be the case that (whether for good reason or bad) we are headed towards low or (better) zero emission at the point of use as a means to improve local air quality (at the very least). Suffice to say, it appears to be seen as a good thing.
In order to achieve (2) more folk need to get over (1). The petrolheads will never shift. Many other doubters won't willingly shift without coercion, because they predict it will be unmanageable for them. As an EV "convert" of over three years now, I can say with absolute certainty that for my lifestyle/driving pattern the changed mindset does work; that range-anxiety and "refuelling" time are not an issue. I have made it so for myself. That was my determination when I changed. And many (but not all) others could do the same. It is only from actual experience of relying totally on an EV that I have come to this position; by being voluntarily "forced" into it. That drove experience, and from experience comes understanding.
Those who are, like me, already convinced, will already have obtained or be planning their own EV. As to the rest - the only way to make more people go EV is to coerce them. Thus, there are incentives available to local authorities and (presumably) workplaces to make these provisions. Yes, it's a subsidy paid for by other taxes. But then, that is how governments manage people in all aspects of our lives. It won't last. Once we achieve a sufficient critical mass of EV owenership and use, these things surely will wane as the objective will have been achieved. And a good proportion of doubters will have found, through experience, that they can indeed manage an EV life for themselves, far better than they imagine they could.
