The smaller affordable EVs are not available in the North American market. The only choice North American consumers have is the large over the top unaffordable EVs. If consumers literally have no choice, surprise surprise they do with what they have access to.

Incentives in this sense really do nothing except subsidize luxury cars for the rich. Cheap EVs are available all over Europe and China but they are purposefully kept out of North America.

There is no political will or interest to actually switch over.
