Moxnix,
I think your idea would bring broader audience base to the sport, but the implementation of such a task would be monumental.
Instead of what ifs, and generalities, please give us a specific plan to think about.
This would only be for the mile/kilo? Why not separate categories, for the different venues, such as 1 mile paved, 1 mile dirt, 1.5 miles, paved, 1.5 miles dirt, 3 miles salt, etc.? If not, the 'fastest' XXO/BVGCC is simply the fastest speed ever ran by run, no matter the venue?
What's your idea for class standardization? All participants agree to build the car to the 'strictest' set of rules currently being used? I mean, for example if SCTA has the strictest rules, everyone worldwide follows them, irregardless of the venue they are running?
Where are the extra fees going to come from to fund the record keeping and such? Would I mail my $400 pre-entry to the SCTA, and $100 to this 'worldwide' organization?
I'm not saying it's not a cool idea, but there are lots of unanswered questions, that need to be answered before a serious discussion can be had.
