Wierd driving lady

Today, there was a lady in a car.  And she was driving, and did a u turn in a road.  Only stopped so that she was at a 90 degree angle to the way she should be facing.  Across both lanes.  And then she checked her hair in the mirror in quite a care-free manner.  

I checked in the back mirror as i drove away and she didn't move. 

I don't even know if that makes sense, but it was very odd looking.
