Pretty accurate assessment, but I am less cynical. I started bike commuting 8 years ago around BTWW, with the intent of doing it every now and then, and pretty soon was biking to work almost every day. However, I was already an avid cyclist. In that respect, the biggest impact of BTWW might be to get more recreational cyclists biking to work. In my experience, very few weekend warriors and group-ride aficionados bike commute or even attempt it. There seems to be this mindset that bike commuting is more dangerous than participating in the average group ride, which is actually the opposite of the real situation, IMHO. Some of the local bike clubs around have regular crashes on group rides, sometimes with serious injuries, yet I have had no casualties in 8 years and 32,000 miles of bike commuting.
