Maybe lithium-ion batteries in mass-market vehicles aren't such a good idea. We may need a battery technology that can survive poor maintenance less than perfect battery construction, and low-cost vehicle designs. Tesla had to put a titanium plate under their battery. That's not a mass-market solution.

BYD is converting over to lithium iron phosphate, which is much better behaved when damaged. Toyota is working on solid state batteries, which hopefully don't catch fire.

The NYFD reports over 55 electric bike and scooter fires so far this year.[1] Two deaths, 60 injuries, including 18 firefighters. Fires destroying electric bike shops are a thing, with one fire expanding to all the batteries around. All we need now is for a cascade auto battery fire in a parking lot. Or, worst case, a garage under a building.

Boosted skateboards used to use lithium iron phosphate, but were just too expensive.
