Exploding cars!?!?

WTF?

Cool, but
What is it doing in the song?

I think it's just here to drive home the general sense of "really strange" and "world is falling apart". Not sure though.

How would a car explode? (sure, incinerate isn't exploding, but explosions are more fun!)

Like this.

I was expecting something like the above when I started on this. The actual story is a little less amusing and dramatic:

Sad explosion.

Still, I wouldn't want to be in either of those cars!

 The Pinto does this because of, in essence, bad design. The way the gas tank was built, in a rear end collision, shears some valve apart, letting gasoline out of the tank and into the accident. With that much metal colliding, you rapidly get a spark and, boom!

However, there are some dissenting voices. Apparently, the Pinto doesn't do this any more than some other cars, and the deaths attributed to this particular type of crappy design are outnumbered by deaths from other crappy design choices. An absolutly abysmal car, but not any more deadly than most others. However, it does have an elevated fire risk.

Where can I get a Pinto to try this?

Blast! Kelly Blue Book only goes back to 1990! Elsewhere it is...

Hah, internet! I win. The 1976 Ford Pinto would run me about $4,800. (a link, but it might break if the car is sold) However, that is a bit beyond my resources. Oh well. The Pinto I found was in South Carolina anyway (York, to be precise), so it would have been a heck of a trip. That price could be high, there are some auctions, and an older one, as long as it was driven, sells for around $1,000 ish. In any case, Ford Pintos are hard to track down.

Have the Mythbusters done something about burning/exploding cars?

Yes, of course.

Yup. Except this is a hollywood movie myth, not a pinto. Oh well.

How would I put it out once it started burning/exploding?

It looks like your standard ABC would work. You can't use water, because that'll just spread the fire. If you're in a high tech mood, you could use purple-K, potassium bicarbonate. However, you'd need a lot more than one extinguisher and more than one person. From those videos, and depending on how much gas was in the tank, it could be a pretty large fire.
