I just posted that pic because it was one I found of that type of lane. Watching for doors opening still seems safer to me than going around cars that are parked. They could be opening doors, too. Getting out into traffic may be the best way on low traffic streets, but on many it is too dangerous. Sidewalks are wide enough for both a bike and a pedestrian. I use them when I need to. My best riding places are low traffic or dedicated bike trails.
I rode with some people the other day that wore those flaming yellow shirts. I could really see them. I am thinking about buying one even though they are pretty loud.

Do any of you wear them?
