Seems like a great idea to offload risk if you're Bird though! All those hoverboard battery explosions a year or two ago (and for example the FAA baggage bans that came as a result) really soured the image of chinese battery electronics.

Defining the heuristic now: the scooter market will truly be "mature" once Bird et al start incorporating commercial fire insurance add-ons into their charger programs, kinda like how Uber started providing commercial driver and liability insurance.
