I have "seen" a handful of car fire aftermaths where it was not only impossible to tell what kind of car it was. It was impossible to tell what "style" of car it was...
Fire will destroy if you let it. Gas, Li, etc. it doesn't matter. The car fuels itself.
Yes, but it's very rare to see a ICEV gas fire where there's a full melt-down of the body and/or frame. There have been MS fires
where all that was left was melted Al.
