Once nice thing about that Vermont lake case is - assuming they salvage the wreckage before the lake melts and Tesla is allowed to inspect it - it should be easy to confirm or deny. The titanium armour plate shouldn't melt from the battery fire. It should be recoverable, and any denting or puncturing from the claimed (delayed-action?) lake rock would be visible.
Tesla would also be able to see if there were any other sources of puncture (e.g. a bullet or whatnot) and test for accelerants in the wreckage (normally finding gasoline residue in a car wouldn't be suspicious, but in this case... ).
