So why isn’t Danica fighting with anyone who “wrecks” her like she did in the past few years?

I think she needs NASCAR much more than NASCAR needs her. It really is the big leagues in US racing and I think she wants to be a part of bigger glory and paydays. Also I believes she can only get by on being cute and doing okay in the results for so long. her record hasn't shown she can produce and I think she knows that there is no room for her to stir up any trouble. There already probably a lot of people who resent that she gets so much attention without producing.
