Caution: more bikes on road

I just checked out this clip on MSNBC.

It seems that people are riding bikes more than ever - as a substitute for driving. I guess $4/gallon was the tipping point. That's a good thing if that's what it takes I suppose. It was an interesting point in this story that people are trying to tune up their existing bikes, rather that purchase a new bike. Of course, the story was shot in Minneapolis which has a huge bike scene. So, everybody already has a bike - it's just that gas was too cheap?
