@MartyCormack @meganL @ascentale @cpm @bikenite apparently worked very well (didn't quite make it to statistical significance, but otherwise a good study, N was large not not large enough for something as uncommon as bad crashes). So, hi-vis, meh, lights, good. I think most drivers see us already, but lights help w/ inattentive drivers. Third, from years of both driving and biking, sometimes at night, I think that driving a car reduces your ability to see. It's too fast, /
