I think you have to understand the difference between racing and spectator sport. NASCAR is most definitely the latter. Everything is geared around the spectacle of the event and making it appear that it is a close 'race'.
Even the off-track activities are carefully vetted by the officials in order to make the 'racing' closer. If an engine manufacturer comes up with an improvement, the NASCAR body will only let you use it if you are uncompetitive. If you've been doing well, then you have to keep your mod on the shelf until they say you can use it.

When was the last time you ever saw someone dominate in NASCAR?

On the other hand, they have a large proportion of the public watching their events, and make a whole bunch of $$$ in the process, so you can't blame them.
