That link went to a story with practically no information. There could be many explanations for what happened, many of which could involve errors on the part of the biker. If the crash WAS caused by an error on the part of the biker, that slants the statistics. How many crashes take place with bikers who are making mistakes (running stop lights, unlit, not yielding right-of-way, etc.) and how many take place with bikers who aren't. I would think that if you are in the latter class your risks are even lower than average. But I'm not a mathematician.
