Remember your location while riding.
This morning while riding to work I had a school bus pull out in front of me (I was crossing a tee intersection with the right of way, he had a stop sign) so close that I could have touched the bus. Between trying not to get run over while memorizing the phone and bus numbers, I didn't remember the street names we were on when he pulled out in front of me. Knowing the exact location may have helped when I called to complain (although the woman that answered the phone sounded like she wished I hadn't called at all and couldn't have cared any less), I just couldn't remember the street names even though I've gone by there for years.
So learn from my mistake as they say, and know the names of the streets on your routes so if you ever need to call and report dangerous driving like I did or better yet, get a video camera to record your trip.
