Pedantically, but importantly, he wasn't wearing PPE (personal protective equipment). He was wearing a helmet and a hi-viz jacket. A helmet isn't PPE, as has been pointed out many times on this forum. In any case, the sort of PPE that protects a cyclist meaningfully from the aftereffects of being dragged under a lorry's wheels hasn't yet been invented.
And the incident occurred at 1:30 in the afternoon. Lights and a hi-viz jacket aren't required. And even on a grey February day, hi-viz jackets and lights don't really make a meaningful difference, and to call them out teeters dangerously close to blaming the victim. All drivers should always drive in such a way as to be able to react to road hazards, and for a driver in London, a cyclist really shouldn't be unexpected.
Without wishing in any way to detract from the horror of this single incident for the victim's family, it's important to put it into context. Cycling in London is really very safe indeed.
If we wear things to help prevent some form of injury and or the elements be it in cycling or other sports or maybe in your occupation , then in my book if the individual is trying to protect themselves from some form of injury , heat, cold, getting soaked , or whatever , then it is personal protection from what ever they are protecting themselves from , equipment could be argued is a multitude of items ,
Just because things have been pointed out on this forum does not mean that the deliberation of these pointers are absolute ,
Also , cycling in London is safe-ish
I rode to London today for the stop killing cyclist meet, I was accompanied by
@jefmcg , I had a very close call with a white van on the CS8 heading back , and
@jefmcg told me whilst waiting at lights there had been more , so safe-ish is how I would describe it
And yes , I was wearing my PPE ,
Helmet , Hi vis , gloves , Lights flashing , waterproof footwear
