Quotes from it:
The survey results included a photograph of a child being hit by one of these moronic cyclists. One could observe that if this continues unchecked someone will get killed, but it is too late: pedestrians already have been. In 2022 there were 462 reported collisions between cyclists and pedestrians, up from 308 in 2020. Some of the ugliest involved pensioners, and as well as jumping red lights, cyclists were seen breaking the speed limit and riding on pavements.
The article is behind a paywall, but it almost exclusively focuses on the danger posed to pedestrians, and not only from cyclists, but also from scooters (which seem to be the worst) and motorists.
