I can't get very excited about this. Deaths in cycle-pedestrian collisions are mercifully rare, as the Guardian report acknowledges; I think the average is three a year, although that would include cyclists killed in such collisions, and the Guardian quotes only pedestrians. Logically, you'd think that the cyclist and the pedestrian would be at roughly equal risk.
What's more, it can hardly be the case that someone is demonstrably and sufficiently at fault to warrant prosecution in all of those. Last I heard, fourteen in every fifteen such collisions happened on the road, for example, so only one every five years on the pavement, where the cyclist is almost certain to have some or all of the fault.
It was an odd aspect of the Alliston case that a major factor was having only one working brake (the fixed wheel). As a driver, I'd expect to be prosecuted for having inadequate brakes, but I'm not sure whether death by dangerous driving or some other charge would result if there were a fatality. But then what other charge could be used? I do notice, subjectively, that there seem to be fewer bikes around these days with no front brake - I saw my first one for ages this week.
