NASCAR is a joke, it has become the professional wrestling of the motorsports world, it's almost down there with the mindless monster truck B.S.
They need to quit trying to put on a "show", and go back to racing. While they're at it, they need to put stock back in stock car racing. Go back to the rules as written and applied in the seventies. Real V8 RWD two door mid size cars, made from a "body in white" as purchased from the OEM. Sure, put them on a 2"x3" racing frame with truck trailing arms. But the car the body came from needs to meet the wheelbase, track width, and other required dimensions as produced. If it were me, I'd make them run a production engine, too, but I suppose the current engine rules are not anywhere near as horrific as the body "rules".
And if an OEM doesn't want to build a car that fits the rules, too damned bad, they can stay home and keep their junk off the track. Those tapered like a turd 4 door shapeless jelly bean cars need to be banished from stock car racing. If you need to screen print the make of the car on the front of it so the fans know what it is, you're doing it wrong. Any manufacturer that wanted to could build a V8 rear wheel drive mid sized two door sedan that would get 30MPG, if they wanted to. If they built them, and raced them, they'd probably sell a lot of them.
