what are the disbenefits of wearing reflective clothing etc?
1. It furthers the perception that cycling is a dangerous activity requiring specialist equipment, which discourages people from taking it up, which in turn lowers the demand for good, safe, usable infrastructure being built that facilitates active travel for everyone, not just road warriors
2. It continues to feed a false narrative about what constitutes safe behaviour and what is unsafe. For example: There are plenty of motorists out who will happily opine in comment threads under news articles about the actions of cyclists without
any insight into
why the cyclist has done something - worth bearing in mind that ~80% of cyclists also drive, yet hardly any drivers cycle.
3. If a cyclist isn't wearing hi-vis/daytime running lights/helmet/beacons that broadcast to cars/anti-vehicle-forcefields/magical fairy dust then it's OBVIOUSLY their own fault that they were killed COMMON SENSE INNIT (even though you don't have to look far to find cases where a cyclist was killed by a driver who was texting moments before the crash on an open stretch of road and who subsequently deleted the messages)
Since Latin is apparently
de rigeur here:
Carthago delenda est.
