its moreso that EV firefighting is a bit different than gas vehicles. if an EV fire pops up in an heavily enclosed area (e.g underground parking lot), its be significantly harder to put it out. basically EV parking will likely be banned in these areas until Liion batteries get replaced by salt ion, solid state or alternative battery that is not flammable.
China generally has high product safety standards on paper, but repeated failure to enforce such controls on the ground has sparked widespread mistrust of homegrown products, and a lack of official information often leads to panicked reactions among the public.
To be honest, well get there too. I only hope that we get into safer battery technology before we have parking structures full of lithium ion battery banks.
