Some lights would also be nice. Car roads get lights, why not bike roads?

I've commuted between the Google campus and Santa Clara by bike, via the Bay Trail, before. I didn't mind the unpaved nature of the trails, I was using a mountain bike. It was fast enough. On the way home after dark though, a little scary. I was quite surprised that I was not eaten by a Mountain Lion. I was more surprised by bikes going the other direction with no lights whatsoever.
