A frightening thought! Not so much batteries; more incendiary bombs.

That's why we charged our RC lipos in a fireproof bag...

Yeah.  A lithium BEV fire has no problem melting the girders of a big
parking facility, collapsing same.

But there is also a building Code problem on exhibit.  In Baltimore,
where row houses are very common, it used to be that the wall between
adjacent was just an ordinary wall, so if a fire started in one unit,
the whole row would burn to the ground. 

So, the Building Code was changed to require a double-thickness
masonry (brick usually) wall between units.  This almost worked, but
the brick wall stopped at the top of the rooms below the attic, which
was still in common.  So, fires still spread to the whole row, only
slightly less quickly.

The Building Code was again updated, now to require that the wall
extend a foot or two above the roof (which was sloped flat).  Success
at last. 

Units now burned independently of one another, and the Insurance
Companies stopped threatening to exclude most of the housing in
Baltimore from house insurance.

I wonder why the UK didn't learn this bit of history.  Maybe those
units were grandfathered in.
