I've unfortunately had the need to use an extinguisher on a burning collision I came upon. It was a small fire extinguisher but it kept the flames and heat away from the trapped driver for a few seconds which fortunately was all that was needed until the truck driver came with a larger one and then I was able to reach in through the flames/smoke/heat to unbuckle and pull the driver out through the passenger side of the truck. I have an extinguisher in every vehicle now, not for property saving, but potentially life saving. Those Elements look great, although pricey.
