I'm trying to find the video of the incident but I can only find stills so I can't comment on the nature of the accident. I have seen quite a bit of comment that he was wearing dark clothes, failed to use a cycle lane, was on a bike so what did he expect, etc. What I haven't seen is much about how the driver was not paying attention to other road-users in front, maybe changed lanes without looking, maybe deliberately tried to intimidate a cyclist (which happens all too often).
Advice to wear bright clothing while cycling or to use a cycle lane is just that, advice. Cyclists have the same right to use the public highway as car drivers. In fact cyclists were there first, before cars existed, and roads were not provided for the benefit of car drivers alone. It's up to the car driver to look out for the more vulnerable road user.
Saying that it's the fault of the cyclist that they were hit because they wore dark clothing is on the same level as saying it's a woman's fault that she was raped because she was wearing a short skirt. It's victim-blaming, pure and simple.
