Today I was driving in the left lane on a local 4-lane street with traffic in all lanes, pretty normal situation. I noticed in my rear view a motorcycle going very fast coming up behind me. I switched on my turn signal and began to move over into the right lane so the speed demon could pass in the left but the guy was ALREADY passing me on the right, we're talking like one second here. As I was in the process by that time of switching lanes I nearly sideswiped him and he jammed on his horn as he sped past me going extremely fast then turned around on the bike and gave me the finger.
I see a LOT of people on motorcycles speeding and jumping lanes between cars, just crazy behavior enabled by the type of vehicle. I'm pretty sure that many, many of the motorcycle accidents and deaths that occur are actually caused by the motorcycle rider.
