Time to talk about "thermal runaway" from lithium ion batteries in electric vehicles...say 50 electric vehicles parked together under a multi storey building...one catches fire, the "thermal runaway" soon sees them all on fire, the steel in the concrete melting and the building collapsing.
Google "Felicity Ace"...car carrying cargo ship, carrying electric cars etc from Germany to USA...caught fire, sank...some are blaming "thermal runaway" from a failed lithium ion battery that spread fire to all the vehicles.
