Listees:
I am , along with a few others on this list, a Professional Firefighter.
So I'll give my opinion here.
Self help is really important. Shut off the engine (Duh). If you can safely
put out the fire with an extinguisher (or two) ...Great!
BUT....don't forget what's really important here. Protect and secure the
safety of yourself, your passengers and others before attempting to
extinguish any car fire. Flag down or get others to help as you deem
appropriate...most highway fires are too far from Fire department help for
timely intervention...call them anyway...surprises do happen.
Approach any car fire with caution.
Opening the hood in some car fires could be FATAL!
Smoldering wiring harnesses can erupt in flames with an influx of fresh air.
A synopsis of some of your comments:

This is generally a waste of a good extinguisher. At best a shot from under
the engine and up MAY work. On our beloved vans the German's provided us
with a wonderful little extinguisher port that also doubles as a license
plate holder and dipstick hatch.

Yep, good advice! In non vans...pull the remote hood latch and shoot under
the opening. Once the extinguisher starts to unload....STAY LOW & LOOK
AWAY... debris and smoke and sparks may issue forth...not good for your
future health.

I have seen passenger cars take a full booster tank (500 gals.) and ten more
minutes of full straight stream and fog (another 2500 gals.) to put out the
flames.

As above...
The second extinguisher might make the difference in an engine
rewire/rebuild and totaling the van.

In my experience people DO give a s___; they just don't know what to do. The
majority of people that do stop will stand around waiting for something
/someone to goad them into action.

Absolutely correct, BUT other things do explode; as witnessed by Chris
above. What many of us consider normal cargo/stuff in the back can really
hurt you if impinged by flames...
Any kind of spray can (paint, WD-40 etc., tar/bug remover, etc, etc);
glass containers; canned food; and then there's the gun toters who won't go
anywhere without their pieces.
The car's interior also provides a lot to the fire load and once ignited
will power an inferno for quite a few minutes.
Additionally, for those of us with alloy wheels; if your van goes up in
flames and is lost , just step back and stay away. If these wheels catch
fire, a whole fire department will have trouble extinguishing them. We just
cool and contain and let them burn themselves out ( Class D ).
I have seen far too many car fires.... the worst are the fatalities!
HTH.
