Interesting thread

Every fuel truck I have seen carries two fire extinguishers on the sides or behind so that any fire around the truck can be fought and stopped before reaching the truck.

In the same line of thinking, I agree that smaller fire extinguishers are no match for car fires but still maybe useful to stop a fire from reaching the car.

And then again, it can be used as a deterrent for an attacker or such.

You maybe sued later.
