I just want an inexpensive commuter that gets ~150 miles per charge. I live in a cold climate and I work about 25 miles away, so I need at least 75 miles range on the coldest days. I also want it to be cheaply repairable, so the battery pack needs to be inexpensive to replace.

Tesla isn't offering that, their battery packs are too hard to service and too expensive. So I'm going to keep driving my hybrid until someone makes something to replace it.

Those Chinese sodium-ion batteries look like the perfect solution. Inexpensive, enough range, and less fire risk. My company says they'll be putting in chargers, so I might be willing to go down a bit on range. If Elon wants my business (he probably doesn't), he needs to make a cheap commuter.
