Nascar , like every other racing type is spec . They all have rules to follow , some of Nascar's have turned it into a clown show sometimes , but you can't say the drivers that go out there aren't the best at what they do . Everybody is on a new learning curve , so with the new rules the racing is dicey until they have enough information to sort the handling out .
I like watching just about any type of racing until they start complaining about how close to each other they are , just separating the men from the boys . Go to any local racetrack on a Saturday night and see how real racing is done , side to side , wheel to wheel , bumper to bumper , fighting for position .
Indy is a joke , only 1 car and 2 or 3? engines , Formula 1 is a close second (talk about spec racing !) .
The guys that really impress me are the rally drivers that throw those cars all over the place trying to stay on the road and at speed .
But , like everything else that's just my opinion .
