No, not riding backwards. Volunteered with my stoker at the rest stop for the N.I.T.E. Ride (N.I.T.E. Ride - Home - Central Indiana Bicycling Association) in downtown Indy last nite. Driving home through the deserted city streets at 2:30am (we are NEVER out this late) came across what I had read about on BF but never seen in the real world - a fellow riding his bike with a flashing white light on the rear and no front light.
Does not compute. Why would anyone think that this is a good idea? While driving behind him, I could imagine someone being confused about whether he was coming towards me or away from me. I knew what I was looking it and it still was a bit disorienting.
I could accept his action of blowing through the red light that we stopped for at an intersection of three streets because those streets were empty. But the little white backwards flashing light blew my mind.
