If we ignore the cultural issues with Americans where some places buying an EV is considered "gay" (because that is inheritently negative to them) then we can easily point to the hostile lobbying tactics and government capitulation via bought congressmen. Go look at the historical hostilities Tesla faced when first trying to take off.

If I still lived in the US, I'd be hesitant to buy an EV because the infrastructure state to state to support charging wasn't great when I was last there. In Europe, you can road trip with your EV no problem.

Let's not entirely blame consumers for not being incentivised enough. Let's face it the US has been actively against EVs. You mention subsidies, haven't those even seen regressions in EV and solar panel subsidies? It's ridiculous.

If the US government quit subsidizing oil companies and traditional automakers, there’d be more incentive to make good, affordable EVs, and more incentive for Americans to buy them.

"Americans where some places buying an EV is considered "gay""

They would jump on EVs in heartbeat if Trump told them to.
