Strategies for a fast attack have the backseat firefighter masking up on a car fire. Car fires are going to give you nasty black smoke. Smoke from a car fire is going to be 10 times worse than smoke from a structure fire.
He’s pulling hose while you’re doing a quick 360 of the scene and talking on the radio and masking up. Start that attack at 45 degrees, shooting it underneath and hitting the ground fire. Until the car is cold, even if it’s warm, it is still off-gassing.
You want to attack from upwind and uphill if you can. Then have a mask on, even after you have knocked it down.
