That's the problem in the OP -- EVs in the US sell only when they are premium vehicles. Cheap EVs don't quite drive like a Model 3. People don't buy a Leaf over a Prius Prime because of a better driving experience... and something cheaper than a Leaf is going to be similarly utilitarian.
Then we are pretty much aligned? I don't think, at least in the USA, that cheap EVs make much sense. The value proposition definitely changes in other countries with higher gas prices.
Yeah, gas prices are having less and less influence in what cars people buy. The overlap between [people squeezed by gas prices] and [people who demand cars from automakers] is dwindling. Fun fact, only about 26% of cars sales are new cars. The vast majority of drivers have no say in what is made.
It is possible to make cheaper cars, but they aren't competitive against nicer used cars. Back when cars didn't last very long it was viable to sell a car with basic amenities, like keyed locks, roll up windows, a single exterior mirror, no stereo, no AC, etc. But now, few are going to pay the prices that would demand when a used car for around the same price has all of those features. This pressure extends to cars of any drivetrain type.
