I actually agree that it's all about money. An average citizen cares for environment in abstract, but not enough to pay premium for it. What we have in Norway with EVs is government incentives for adoption at work.
With biodiesel I remember there used to be some debate how much it can harm the food crops supply if the prices are competitive. So at least that is a concern. And specifically in Norway diesel is penalized for a while now, ironically after being promoted by the government for years before that.
There was some old regulations on the books that allowed EVs to drive toll free and use buss lanes during rush hour.
Hardly anyone cared when it was introduced, because the major EV available were Think compacts.
But when Tesla introduced their sports car, suddenly everyone monied individual in the cities took interest. Because it was still a EV according to regulations, so now they could drive something that looked and performed just like the gas guzzler the neighbor had, get around tolls and rush hour traffic, and pretend to care about the environment.
