Gasoline and diesel vehicles can certainly catch fire but rarely do so when they are just sitting unused (although there was a recall on Fords a few years ago because the ignition system would spontaneously catch fire); most car fires are due to fluids leaking from the head gasket or oil system dripping on the engine or exhaust manifold. BEV fires, on the other hand, can definitely occur during charging. A number of commercial insurance companies require additional riders or just don’t allow charging stations in underground garages for that reason.
