I've seen videos of EV fires. I've also seen an attached garage fire with a non-EV car – it was so hot you couldn't comfortably stand across the street from it. The house still survived due to the cinder block wall between the garage and house.

Still much less spectacular than the natural gas explosion I once saw... The house that actually exploded was just gone, and every house around it had to be torn down due to massive structural damage. But that explosion was intentional insurance fraud.
