Not sure how those stats are relevant, unless cyclists need to leave a trail of dead pedestrians in their wake before licensing is justified. Personally, I think a trail of angry pedestrians is quite sufficient.
Off the web: “This is something that gets on my nerves. On my ride, just about every other cyclist I come across is a pavement cyclist. I had a go at one today on my way home, he must of been doing quite a bit of a pace along the pavement, which is used by school kids walking home.”
