Looking at what's available in Ireland at the moment, in the 20-30k range there's a Nissan, a VW (though it's the ancient e-Up, due to be replaced by the i2 any day now), a BYD, a Fiat, an MG, and an Ora (tragically no longer under the names "Good Cat", or "Funky Cat", presumably because Ora got around to hiring someone who had heard of marketing).
There are a bunch more in this price range due to launch next year.
Cheap-ish electric cars exist, they're just not, generally, suited to US consumer preferences.
If the cost is low enough, compromise on range becomes acceptable. I might buy a small, cheap EV that has range enough to handle my typical daily driving. But if I'm paying Tesla prices, it will need range to handle virtually all of my driving.
That'd be perfect for me to be honest. We have a Tesla Model Y which we can road trip in. I'm just looking for a slick, efficient commuter. I normally only charge my Model 3 to ~60%, which is ~150 miles of range anyways.
