NASCAR LOSING VIEWERS DUE TO TOO MANY RULES

I use to watch NASCAR religiously every race. I have seen two races this year. I have lost interest due to the rule changes constantly. I heard the latest was the cars could only use one transmission or rear gear set up per race or they go to the back of the field. I wonder how thick the NASCAR rule book is. There must be a huge one for each different track. It isn't a lot of fun to watch anymore.
