"Soccer mom" is used to describe moms who spend much of their time shuttling their children (and other people's children at times along with their own) around to athletic events, typically driving a minivan (SUV also now).
I've used the term as far back as the 90s when I played soccer and the season meant my mom was driving all over the place for us.
I've applied to term toany mom's, even my wife now, as sports hasn't changed that much in this regard. Incidentally, baseball proved to be much more driving this year.
Not once, to my recollection, have I applied it negatively, or in the way you describe. Interesting how you define it though.
Edit: I found this urban dictionary description that seems to fit your view of soccer mom's better
