These are controversial cars for sure and the comments here are pretty telling: they are by one comment too slow (when driven legaly), and by another too fast for safety (when driven illegaly). I have helped a friends son with such a coversion this year: It doesn't take that much really. Just an electronic box that kills the spark coils when the box senses that the drive axel is spinning too fast, and a big plywood box to make the back seat unusable. Electronic conversions where made simpler to put them more in line with the EU moped car class (except those can do 20 km more per hour). I think one recent trend is that these cars are not primarily a "out in the sticks"-thing any more: Most new conversions are done by (small) town kids, who drive around in the town, not out on the dirt roads.
