alt Hacker News> I think that the odds are quite high that a 3 years old child will get hit by a cyclist
You should see the odds of a child being hit by a car! Here in the US, about 6 children a day are hit and killed by a motor vehicle. And yet the number of children hit and killed by bicycles is unavailable -- perhaps because it is close to 0?
I understand that "as a father" you may become paranoid about things that are objectively unlikely. But if you are more worried about getting killed by a bicycle than by a car -- something 160 times more likely to kill you! -- then perhaps you need to recalibrate.
Thankfully, cars don't ride on the sidewalk. Every cyclist, where I live (Latvia), rides their bike on the sidewalk. Including e-bikes that are really electric mopeds (you don't need to pedal). Will the Indian food delivery rider, late and tired after a long shift, notice my son, who jumped to scare a pigeon? Let's find out!
So, your statistics are worthless if you don't take the context into account. And even if "there is no risk" (virtually), I'm allowed to say that cyclists going at 25km/h have no business on the sidewalk where I walk at 5km/h.
Cyclists think just like car drivers, and find it totally fine, since they themselves "feel unsafe from cars who go too fast". Of course the feelings of the pedestrian plebeians don't count for the new noble equestrian and morally righteous class.
