I'm here visiting San Diego, home of one of the most well-known VC advocates in the state of California. The way people cycle here looks the same as anywhere else I've been.
One thing that's different that I've seen is where two busy streets merge together and some hapless cyclist gets stuck in the middle of the merge. I've seen this 3 times in just two days! He's stopped at the point where the merge comes together and is waiting for a break in order to get to the new right lane, two or three lanes away.
So why don't cyclists here ride more like the smooth-sounding VC I've heard so much about? Why aren't they taking the lane so they can smoothly merge through those converging streets? I haven't seen anyone take the lane. Maybe I saw one guy, but it was hard to be sure from my vantage point. Maybe a little "think globally act locally" is needed here in the land of Helmet Head, because VC doesn't seem to be catching on.
