I would be so that all bikes are painted in reflective fluorescent like vests.
It is a real calamity. Far too many cyclists ride absolutely without lighting, even mopeds. Preferably dressed in dark. For them, it does not matter: they are crap at the hospital or at the cemetery, but who is it that passes for a bad guy and all the troubles?
Citro: the instinctor is mandatory, although they rarely look at the CT (when there is an expiration date). The triangle, the first aid kit and the vest too.
