The restrictor plate was just to bunch them up. All the rules are just to keep them bunched up.
NASCAR is racing history kept alive by advertising. I don’t even know who half the sponsors are now.
Koch Industries was the main sponsor of the car Newman was driving. Koch Industries is primarily owned by the Koch brothers. They own companies like Georgia Pacific, manufacturers of lumber, plywood, osb and other building materials.
Just an example of a advertiser of products that probably a lot of NASCAR fans use. Just like Lowes, Home Depot and Menards are other car sponsors. Their target audience is NOT metro sexuals living in NYC. They are advertising to blue collar working men and women.
I have attended the NASCAR race here in NH. 100000 people show up for the race. I would estimate it is about 3/4 men wearing baseball hats. Except the hats say Chevy, Ford and Toyota, not Red Sox. Although, Rousch Fenway racing also sponsor a car.
