DLS was like a light switch not only terms of lighting conditions but stupidity factor of drivers. So many close calls that day on the ride home. Almost had an accident occur right in front of me as a truck towing a trailer moved into the left lane to give me room and then this compact car proceeds to zoom past in the right lane. The truck having passed me tries to get back into the right lane to make a right hand turn and almost pushes the compact car into the curb (which did not have the light on BTW). Almost missed seeing two cars behind me while making left hand turns because they were driving around without their lights on.
I know the etiquette is to not have blinking lights on at night but I felt like I HAD to that night and turned ALL my lights blinking. On bike, on helmet, armbands.
