I was always under the impression that water and fuel don't mix since the fuel will float on the water. So this moronic idea of dumping water onto a fuel fire is absurd unless there is a foam mixed in with the proper applicator.

Methanol and water mix. Methanol has its own oxygen to burn so it doesn't go out with "normal" smothering techniques like dry chemicals. The general idea is to dilute the alcohol with enough water to render it less or non-flammable AND cool the surfaces that might be vaporizing the fuel and fueling the fire.
Gasoline does float on the surface of water and drenching a gasoline fire will cool surfaces just as in an alcohol fire, but it does have the potential to spread the fire over a greater area.
So, dousing the car with fuel isn't the worst thing you can do.
When Methanol was first allowed, it caused a lot of concern because of the need to have two fire fighting systems. At least you knew that the kind of fuel being used was consistent within a class, i.e. sprints were running alky, but stockers were on gasoline. The unheard of practice with mini-sprints has been that you could run either fuel within the same class (a weight break for gasoline cars). You simply put lettering on the car stating the fuel type you're using. So EVEN IF the track crew had both types of fire fighting equipment, you don't even know which kind of fire your dealing with until you come up on the car and read the lettering (which of course is stylized to match the other lettering and may not be that legible) and then fight the fire.
There's a reason USAC helped develop and mandate bladders after the Salt Walther Indy fire that burned so many fans. They work.
