Biking through downtown

I was riding my bike through downtown during rush hour on a street with streetcar tracks. There were lots of cars and I was worried about getting my tire caught in the tracks or a streetcar coming so I got off and walked.

Then this girl zipped by riding right down the center of the tracks. I figured she knew what she was doing and that I'd be safe if I followed her.

But then when she stopped at the next red light, she fell off her bike.
