I usually just take the lane to save myself any future injuries, but I had an instance where I was stopped at a light, in the traffic lane (no bike lane, gnarly shoulder), and a cab pulled around me to pass as the light turned. His side mirror actually grazed my elbow as I was mounting my bike. He wasn't going fast, but it still knocked me on the ground since it threw off my balance. I called and complained, but never heard anything back from them.
