Been talking with Tim? LolI don't think that would be a good idea Tony. Have you looked at any of the videos on YouTube yet? Be under no illusion that this will be dangerous! A dozen or more karts hurtling down a public road together at speeds in excess of 30/40/50mph depending on the gradient. Wouldn't think it'd be suitable for kids!
Also, because the races are mostly run on public roads the races are held very early (like 7am) on a Sunday morning in order to mitigate any chance of encountering other vehicular traffic on the roads. It is not legal to run a race like this on a public road, hence the "I" for "illegal" in the various federations acronyms around the world. Again, not suitable for kids (barely suitable for adults)...
