This ignores the fact that bikes are so much less dangerous than cars that most crashes that involve a bike but not a car will not be reported. Your average time a cyclist runs into a pedestrian will be only an annoyance.

Also, note that super bike-friendly Netherlands has 1/10th the pedestrian fatalities with 1/4th the population of the UK. If bikes are that dangerous, why would such a bike-focused country have radically fewer pedestrian fatalities?

From what I've seen, the data is pretty consistent, in that more car-focused countries tend to have more pedestrian fatalities.
