We do have active and good referees at nationals and regionals, who do a good job especially helping the leader work through back markers and the like..
but at the same time, "orange car going onto the straight, you've got the leader coming up to lap you" works just as well as reading a number.. if its even possible at the speeds these cars go.
My beef is that I like the look of the buggys, but they are spoilt with huge and ugly numbers, I wouldnt mind them if they looked cool.
and JEEZ, how the hell is a driver going to see out with a huge number on the window ? ?!? THAT is why i dont do well...
