I think the fall of Open wheel racing scared them. You can't just let them build cars as fast as possible and race because one team will dominate and competition will suffer.
Personally, I think they went too far. Yes the racing may be better with more lead changes but I'll miss the Richard Petty's, Cale Yarlborough's, Dale Earnhardt's or whoever of racing going out and just dominating a race.
I think they've been on the wrong track for a long time, why should they manipulate things to make it competitive between manufacturers. Either they are or they aren't that's up to the manufacturer to worry about. After all it's supposed to be the National Assoc. of Stock Car Automobile Racing. It's a wonder they haven't been sued for calling it stock cars.
Would love to see some Stock car racing again.
But, this is what we have and we'll see where it goes from here.
