Motorcycles, Enduros, and Quads are all used on a large scale as vehicles here in Bolivia. I once saw a family of five people on one. A father, a mother, two little boys (6-8) and a newborn baby. NO helmets... It is completely legal, and if its slightly against a law... the police are really relaxed. Driving is crazy... No speed limits, lanes and seat belts are optional and horns are used quite frequently... However amoungst the chaos, I have not seen one accident here. Maybe we have it backwards in Canada? Or maybe its just different...
