It could be useful, at the beginning, but sooner rather than later you’re running out of fuel. A wood gas car is infinitely renewable. Wood gas may not work as well in cities, but in a truly post-apocalyptic world cities are the first to go anyway. In an SHTF situation, such as a country at war? I can sooner believe that, since plastics are more energy-dense than woods. It’s still not all that useful, but at least there is some minor niche it could possibly achieve.
