One solution is to build EVs with quick-change battery packs. That's
what we're trying on the Sunrise EV2. The batteries are in a "drawer"
that slides out the front.
With quick-change packs, you can use a cheap short-range pack for normal
around-town driving. Or swap it for a light high-power pack if you want
to go drag racing. Or a big long-range pack for extended trips. You
could even have a "hybrid" pack, which includes an ICE generator.
This also means you can change your mind later. If you bought the car
with with a short-range pack, but found that you needed more, you could
buy/borrow/swap your pack for a longer range one later on.
It's also a big advantage when it comes time to replace the batteries.
Replacing the pack in most EVs is a major undertaking!
