Fixed gear girl, You are close, but you are thinking of the entrance ramp from Bee Caves onto 360. This happened at the top of the exit ramp apx. one block before that entrance ramp. I saw the outline again this morning and now I think it happened right after she merged from the shoulder into the triangle area that would have kept her going straight on 360. So she would have been clipped on her right side by the left side of the trailer. Does this make sense? However it happened, those exit and entrance ramps are disasters and should never be taken lightly.

Still not many bikers on 360 today.
