I wouldn't be surprised if she doesn't want to be a public personna anymore, and just wants to be a musician. And, if that was her kid in the car crying, then yeah she wouldn't want to deal with photigraphers. Her publicity appearances are one thing; but her everyday life is different. It's as though she's always at work and can never relax. Not that I actually disagree with you, she knew what she was getting in to when she became famous. I just like to separate work life from private life, and I assume celebrities may want to do the same.
