Response number 732 (!) on the TeslaMotorsClub forum about this accident
has quotes from Elon's blog and the email sent by the owner - he did not
quote a time, but from pictures in one of the earlier responses (Google
Map satellite view of the scene) you get an idea that the Model S
traveled quite some distance after hitting the large piece of curved
heavy metal object, since the car had to exit the Carpool lane, get to
the exit (I do not know how far away that one was) and stop before the
intersection at the bottom of the exit - that is probably where the
driver first became aware that the car not only had an impact with an
object and he was directed off the freeway to resolve power loss, but
that the front battery module was actually on fire, why else would you
drive to the end of the ramp and only stop at the light,
exactly where you normally stop before pulling out into the crossing
road?
So, this EV was still driving with one (of 16) modules punctured and the
fire was contained in that one module due to internal firewalls between
the modules.
Fires always become more spectacular, producing more smoke, by random
things that burn and give lots of smoke, such as tires, hoses, carpet
and some joy from oils contained in the vehicle such as brake fluid.

This is good.  Cooler heads prevail..

means-for-electric-vehicles/ )

As I have been telling friends,  If you rupture your GAS TANK, and there
is ignition, you may have SECONDS to get
out to safety.

Puncturing the battery pack on the TESLA-S probably caused a series of
shorts, and wires and batteries had a "thermal runaway"

  I would LOVE  to know the time-line from the owner.
 From the moment of striking the metal on the road
to the first sign of a problem, to the first smoke, and finally catching
other stuff on fire.

Any one out there in the TESLA community can add these facts to the
situation ? ?

  I would guess several minutes or more.
