Last night lighting the way on the Greenway for a road biker who was out too late, I felt bad about turning off at my exit. But also relieved because it seemed like he was all over the place behind me, pulling up beside me a few times, and it was making me nervous. It might not have been that bad and just seemed like it because I couldn't see him or hear him and he never said anything. I slowed down to make it easier on him but then I sensed him yo-yo'ing back there, which felt a little creepy.

To me it seems to work a lot better when I stay behind someone and turn it up to bright.
