I'm betting you were going 15MPH+

Cars don't realize how fast we move. They think of bikes moving the same speed as pedestrians. She saw you as she approached you, figured she was *well* (and safely) past you based upon her perception of your speed. As she took the right turn, she didn't look and didn't see you because you don't look for vehicles on your right when you are in the right lane.

Glad you're okay.
