The Aptera looks interesting for that sort of space. You might be able to option it with the lowest battery if you don't care about range and with the largest solar panel option and perhaps never/rarely even need to plug it in. Of course, they have to actually make it to serial production first, but it's a really neat concept if you value efficiency in your transportation.

Now that is exactly what I am looking for. I picked all the lowest options, and it comes to $26,000. I'll definitely keep an eye on this company.

GEM makes something that fits your bill.

In my state, they can be driven on roads that are 35 mph or less. That’s sufficient for many urban areas.

So... a 12 year old Leaf? The old ones suffered severe range degradation and tend to be cheap second hand as a result, but should probably still do 50 miles.

Sounds sort of like the Citroen Ami? Slightly below your ideal range and quite expensive too but the same concept.
