Wood gas vehicles were, well not uncommon:

Due to the need for oil (major cause of second world war anyway) Nazi Germany produce 1/2 million cars run on wood gas.

Wood gas was really common and used to power all kinds of lighting before electrification. FEMA even created and distributed plans[0] for a Gasifier in the late 80's. You can find the PDF all over the internet, I think its a pretty cool looking project.

Youtube is full of weird wood gas car projects such as this pickup truck: https://www.youtube.com/watch?v=9AFw3Agg7SM

I don't see how these could be street legal in general, but pretty fun.

Saw a few pictures from North Korea using something like that.

It's actually more interesting than I thought!
