Auto Racing is the only sport I can think of where a driver can participate and get paid in multiple levels of competition. I wonder what the stats are, if only 10% to 15% of the drivers in a Nationwide or Truck race are Sprint Cup drivers, of the percentage of wins by those (Sprint Cup) drivers in those races.
Ringers are an excepted common occurrence at (Sprint Cup) road course races. I’m certainly against more regulation but the involvement of who in what in auto racing seems a bit convoluted to me.
I am sure there must be some rhyme or reason why they allow ‘more skilled’ drivers to drive in the lower skill races. I suspect that it had to do with $$$$$$$$$$$$$$$$$$$$$$$ and more $$$$$$$$$$$$$$$$$ for the race track owners. The cities probably encourage it because it means more $$$$$$$$$$$$$$ for them in taxes. So, like most things it boils down to $$$$$$$$$$$.
