It's Show Business folks, get over it.
+1 on the high level of technical sophistication, and driving skill, needed to compete in NASCAR.
Years ago, I was a 20 something, just getting my feet wet with an SCCA G Prod Spitfire.
A local veteran, Dana Barlow, clued me in when I made a crack about stock car racing:
"The cars are in a continual power slide throughout the whole of each turrn. For every turn, for every lap, for each corner, the optimum setup is different, and changing. Tire pressure, compound, camber, castor, toe-in, corner weight, aero, etc."
It looks easy: it's not.

As for carbs vs EFI, who cares? That's infrastructure, the job of the mechanics to make it work, like Klieg lights at a play. When is the last time you heard about a carb issue at a NASCAR race? It works very well for them as-is.
I'm just worried that EFI will allow the race organizers to anonomously determine the outcome with a few mouseclicks, instead of with intimidation, money, and politics like they do now.
