It's all very well but, when you throw an oncoming motor vehicle into the mix, then it's bloody hard to see those pedestrians unless there is some odd light movement to catch the eye.

HiViz does look like road signs - especially when not particularly paying attention (i.e. not 'wondering what that is' for everything in the path of the vehicle). Road signs need no particular avoidance plan, the way something in the road would, so HiViz may get dismissed as 'no threat - nothing to do'. Looking like road furniture in the distance is not necessarily a way to be "conspicuous", although more light does reach the drivers' eyes from the HiViz - so they are 'seen'.
Gareth wrote: I wondered about "particularly since low-beam headlamps will not effectively illuminate retro-reflective material on a jacket" given that low beams effectively illuminate road signs - is this point more to do with what drivers are or aren't looking for, and maybe what they perceive, rather than anything else?
