And yet if you look at the public health statistics for the things _actually_ crippling children for life, "other people on bikes" are a very long way down the list - at least in most places; I don't know if Paris has a specific problem there. You can hurt yourself pretty bad in the home, after all - the major causes here seem to be cars and dogs.
(Before we even consider that - at population level and in developed Western countries - lack of physical activity, and an environment which actively suppresses it through sheer indifference if not outright hostility - is likely inflicting a far greater burden on childrens' health and wellbeing than trauma).
The statistics are low because many places banned cyclists from sidewalks? Purely speed-wise, being hit by a car at 50kmh while riding a bike at 25kmh is similar to being hit by a cyclist going at 25kmh while being static on a sidewalk. Why are cyclists concerned about cars but I should just think "trust the stats bro" when the 5th cyclist going at full speed came past me on a narrow sidewalk? France banned shared e-scooters after many scathing accidents, including deaths and people being crippled. I remember a professional pianist who get her hand broken this way and had to stop her career.[0]
But I guess she's just a statistic, right? Pedestrians, out of the way!
