In Sweden your allowed to drive when your 18 years old. But due to some old rules about tractors one can build a EPA or A- tracktor and drive it when 16 years old. They are only supposed to do 30km/h thou..

Most pepole deny the time with the tracktor but I had fun and it made me start building cars. From the beginning it was a way to get from A to B but soon the building was the main thing.
