The blue Cobra you are referring to belongs to John S and a friend. John seems to think he's above the rules a lot of the time. Funniest thing I ever saw was Bobby DNF him for hitting the cones after the finish beams (which was announced as the penatly at the drivers meeting).
There is something about two driver cars in the SCCA rule book. Neither BCC or TSCC are SCCA clubs, so we have the option to do what we want. Like Beno said, at TSCC we are going to forbid them from being in the same heat unless it's absolutly impossible to do so. I don't know what BCC is going to do about it since I have nothing to do with them.
