Earlier articles about this phenomenon have pointed out that the 40-something riders are also going out on much more ambitious rides early on than are the 16-25-year-olds.

No question that there is a self-selection bias coming in here. That's a huge factor. I also know, howver, that I learned a lot from the class, especially the braking drills. I know that I've prevented at least one single vehicle accident because of what I learned in class. But the old selection bias will continue to confound us until we have a population of about 1000 riders or so whom we're willing to sacrifice to a controlled experiment....>This is a classic chicken or the egg debate- Does the riding class make >people that much safer, or are the kind of people who think a safety >class is a good idea less likely to have an accident?
