FWIW, electric _cars_ at or below this price point are certainly a thing, though possibly not in the US.
So much for 'home of the free market' that between regulatory capture and broken dealership models and import tariffs the competition looks so bad.
When people ask "where are the <$30k cars?" they generally mean new cars, because the more $30k cars that are sold new should imply more <$10k gently used cars on the market. The used market doesn't get cars that people can't afford to buy new in the first place.
