@whylamb yeah, battery technology is fundamentally dangerous at the moment. I think people just don't realize they have a bomb in their pockets or their fancy new bikes and go full reactionary when the slightest flaws get discovered. I don't know the story about the escooters, but my ebike came with several warning pages, including one big one in big text about taking proper care of the battery.
Do you know how far along sodium batteries are? I haven't really heard anything about them.
