First, on the article, I don't have any problem with getting a license to ride my bicycle, but I do wonder how this can possibly be enforced. And at what age do we enforce it? Should 6-year-olds be licensed? What if they can't read yet? Should there be a graduated licensing scheme like there is for driving - maybe one at 6, then 12, then 18?
Actually, the average 6-year-old doesn't have to ride on the road, like big people do, because they typically have bike tires less than 20" in diameter (or 50 cm), which is the cut-off for sidewalk cycling - something that IS legal in Waterloo if the tires are that small. (By-law 08-077, which also says it's illegal for anyone to use a skateboard on a sidewalk. Who knew?) So maybe once kids graduate to a 20" tire they should have to get a license to drive it legally.
