There are always people that will want the latest thing, whether EVs, Apple watches, etc, and are willing to pay extra for that. And then there are the planet savers that will also pay extra, but not for the more expensive EVs. But all these people are still a very small volume.
However, to achieve large EV volume sales, consumers will want a payback (over buying an equivalent ICE version). Unfortunately, those products that best meet their requirements are just not available (in a reasonable time). And, as has been mentioned, gas prices need to be higher.
The Kona is one example that does provide a payback. I bought mine on May 1, when the Cdn govt subsidy came into effect, knocking $10,000 off (incl the BC subsidy at the time) the MSRP. At 30,000 kms per year (my projected usage) I will get a payback in less than 3 years. Of course, the fact that Vancouver has the highest gas prices in North America really helped the equation.
And I obviously wasn't the only one that figured that out. The Kona was sold out here immediately after May 1, and buyers are now waiting until next year on a pre-order.
