It's not the generator itself, that makes the system "illegal"
Cars 87- and newer here have to comply with emissions, (Which isn't also a problem itself, syngas burns cleanly)
The problem is that here in eyes of the legislation (not sure if it's EU or our own law)
Wood gas isn't an accepted/certified fuel for roadway use.
But I se a crapton of interesting cars I could run on wood gas.
And the wood gas is produced on-demand, so ecomodding is still something I would do a lot
reducing consumption is still a important thing, so you can drive further on a X amount of wood, even if it's about 75-80% cheaper fuel than gasoline
