SSS, sounds cool,,,, one small issue on a public road, even if all would work and they closed the road.. we would have to have parking/pit areas...
Also on big safety concern, I would scope out the close proximity of any trees, telephone or power poles on either side of the road / racing and shut down surfaces...Hitting a cone or some tall grass, weeds or crops may be bad,,, but a tree, power or telephone pole could render a bad day for all.
