If one was to “crush” any of the common vehicles full of: ( gasoline, CNG, propane, or diesel ) and compare it to the “puff” of a fully loaded wood powered vehicle, I think we would be considered safer. But of course that will never happen, and we will never know. . . . unless one of you knows someone with a car crusher and a “myth busters” mentality. Hey, maybe we could get them to do it for us. Chrisky can write a suggestion letter, and Terry L can donate his pos. Sorry Terry, I feel your pain brother.
