If you want all the mathmatical calculations to figure out that yes, you can start a fire rather simply, go to the always helpful site, http://www.eatel.net/~amptech/elecdisc/wire.htm . For all intents and purposes, that analogy that the coil on an electric stove turned on creates the same effect that would happen to a shorted wire in a car.
I can't say I have had the oppurtunity of starting a fire in my vehicle, the closest I have come is inadvertently shorting the battery when I (mistakenly) used a rachet to take off the pos battery terminal and kept hitting the body. I would never suggest actually trying to cause a short because the current running through the wire is enough to kill or maim you easily.

I was actually using that site to prove it, but he fails to see it because he once shorted out a battery with a screwdriver. He also doesn't see how the fact that the screwdriver was six inches long and probably had a huge ohm rating would make any difference.
It is exasperating trying to prove something to someone when they refuse to acknowledge the numbers in front of them.

I say let him be thick-headed. The only way that I could see of doing a field test would be to move at the very least 20 ft from anthing that could catch fire and then use a 10 ft length of bare wire that is whatever gauge to demonstrate the concept. Even then, the battery isn't being continually replenished by the altenator. This would be extremely dangerous and the battery has a lot of potential to explode and spew battery acid all over.
Bottom line: Sometimes the only way someone will learn is when they screw up. You don't have to prove what you already know to someone who is too ignorant to understand.

That is what is so annoying about this, he is generally pretty level headed, he just refuses to consider that he is wrong this time. He even asked "friends" if you could "set a car on fire" by grounding out a "12 volt" battery, and he says they all laughed and thought that was stupid.
