I actually saw 3 or more women with the burqa in real life, and I knew a girl that went to high school with me that did wear the burqa when she was outside school but inside she didn't because it was too much and the teachers need to see her face, etc... But she wore an hijab instead when she was inside school. I think that the women that wear a burqa don't go outside really ofter and when they do, then they cover themselves like that.
I agree with the enforcement thing, I had my mom trying to enforce to my sister when she was younger, but she wears the hijab now, so it should be chosen to wear it when the time is right and when a girl is comfortable wearing the hijab...
