There are some cars with panels, but they can only get about 10ish miles a day with good sunshine. Stationary panels work much, much better.

What does that have to do with EVs? The inflection point for adoption is solid state batteries, and there are some experimental factories under construction. (Solid state batteries don't loose charge when parked and can charge about as fast as filling a tank of gas.)

Battery exchanges are impractical because the battery is part of the frame.

I don't think the bottleneck for charging is in the batteries, it's in electricity as an energy vector. By its very nature, someone is either instantaneously dispatching it from somewhere, or it's already being generated and curtailed. I just don't see that being cheaper than even biofuels in the long run, because time arbitrage matters. Making fuel with overcapacity that is worth zero (or less!) probably scales better than trying to store it all in batteries, because holes and containers will always be cheaper and easier to expand.

Never heard of batteries without self-discharge.
