that if a tesla has a 1/4 inch protective plate seperating the batteries from the road it's a safe vehicle indeed.

I was simply sharing my personal experience with ramming 1/4 inch plated vehicles into hard immovable objects to give some perspective as to what kind of strength we're talking about.

The fire in question involved the piercing of a 1/4" plate protecting the battery from below. If that's a thick enough plate to protect a 12-ton boat, which has more momentum than the Tesla even at much slower speeds, with hardly a dent, then the Tesla incident was very, very out of the ordinary.
