I dont know about formula kartways but GPK allows children to drive their karts, they dont have their driving licences. Most of those kids dont know about how/when to overtake or how to keep their position without ruining it for the other person. And what if a kart breakes down on a track, that can also cause an accident, so remotes do come handy. They also have pretty intense race leages where you have to be at least 16 i think and is more serious and way more fun.
