I gather that they exist in China and might be allowed into the US. I'd buy one.
I doubt it's going to happen because that would kill a large part of the market : every familly that needs 2 cars just because they go to work to different places but would only use a single car for the heavy duty or long range needs. At the start it would be a hard sell for many because of social status but overtime people end up voting with their wallet, so it could work. But that would be a pretty bad deal for the industry, so they'll only turn to that if they can't sell anything else.
Nowadays even the smallest cars starts around 20k, which is absurd and it even affect the second hand market because cars maintain their value better thanks to this pricing.
The Nissan Leaf’s biggest problem is it’s the only vehicle in its class worth considering, or available at all, so secondhand ones are sold at whatever the market will bear.
There’s the Prius, but whoever is responsible for its styling will be the first against the wall when the revolution comes.
