Being a pedestrian is no reason not to care about light pollution.
I am a pedestrian too. I have a nasty strobe sensitivity, so I can’t drive, can no longer bike, and can no longer ride the bus. And can no longer cross at busy intersections, because there are too many flashing turn signals, and the things blind and disorient me, and cause me to stumble, sometimes into the street. And can’t go many places because there’s no way there without going through busy intersections on the way. And must often drop errands, because someone’s set up a strobe battery on the way. I suspect it’s related to my sound sensitivity/hyperacusis.
