This is helmet cam video showing a #54 Trimet bus pushing into the bike lane at about 6360 Capitol in the Hillsdale neighborhood of Portland, Oregon, USA. Taken about 9AM, 3/2/2011. License plate E235920, bus number 2915. I was riding my bicycle in the bike lane; I was forced to stop to let him by.
