and can't even get you halfway across the state on a single charge
This is the part that needs to be rethought. Depending on speed and stuff, I can go about 200 miles on a charge. Want to go farther? Fine! DC fast charging is, in fact, fast. Plug in, take a pee break, stretch for a minute, and get a bite to eat. In 20 minutes, you can get a lot of charge in most cars (granted, my Chevy Bolt needs a little more time but that battery technology is relatively obsolete)
We already stop on the road for other reasons. It's not hard to combine stops, and it will only get easier as chargers get built up. Stop pretending we need to drive 500 miles without stopping, that's dangerous anyway.
