There was this time when I was riding on a main street. Two way traffic with on lane of traffic for each direction
and cars parked on both sides. Bus couldn't pass me because I'm in the middle of the lane; away from the door
zone and people jumping out between cars. He also couldn't pass on the other lane since there was a steady flow
of cars from the oncoming lane. So what does he do? Starts honking at me. What do I do? Pull out my cellphone
and hold it in front of me pretending to videotape(riding a bike and actually trying to videotape is hard). Beeping
stops and when oncoming traffic stopped; bus driver moves over and passes with a wide margin.

Taping traffic can also be used against the one filming, say for example jumping the red light
