Another car fire around three miles from my house.

The problem with halon is, out in the open if there's a decent breeze or stronger, You have to be right on top of the fire or jam the nozzle into the flames to hit the source close enough to suffocate it. Whole car systems are relatively contained & there to keep the driver from being killed/seriously burned 'til they can exit/help arrives, a bad spot to be in no matter what.
I personally knew a man that got burned over 75% of his body & Stat-Medivac chopper'd to the ER, they had to put him in a synthetic body stocking to maintain the body temp, & protect from infection. It was months of pain & scares, requiring blood transfusions, it just plain sucks.
I also know of 4 classic cars destroyed by accidental fires, & 2 that sustained significant damage, I feel really bad for this Mopar Owner.....that's a lot of fire & nobody around yet....:(
