Interesting that a good half the cities in the article are college towns. I don't think they're very representative of the population as a whole. But even here in NYC I've seen an increase in the last 4-5 years. I actually count, when I can see them from my train, the number of riders crossing the Manhattan bridge from Brooklyn and it has steadily increased. It isn't scientific, but definitely it is trending up. I join them once or twice a week. I also see when I'm riding that the number of cyclists on my route has gone way up. It went from a handful in Brooklyn to a steady stream, and in Manhattan as I went further uptown there were fewer if any riders. Now there are riders all the way up. Citibike has bumped up the numbers too. You see them everywhere.
But that makes me the type of rider that doesn't really help solve the problem of cars since I don't drive to work anyway.
