(although a vehicle without lights at dusk does seem to stand out like a sore thumb because it's unusual). Just as I'm not making a claim re hi-viz because the proof isn't out there and the evidence is ambiguous.

Read my mutterings:
OK, have a black aircraft on the ground Also, note the hi-viz 'yellow' bit of airfield furniture in the black, sorry, background.
I didn't say - because I don't know - how accurate speed judgements are with and without headlamps.
[I]Shaw [UK] 1979Compared the accuracy with which subjects estimated the speed of a motorcycle with headlamp on, and off.Subjects over-estimated the speed for lower speed of approachSubjects under-estimated the speed for higher speed of approachThe reversal from over- to under- took place between 50-55mph with the headlamp off, and between 35-40mph with the headlamp on.
Two key points there.First, if everyone was using hiviz and headlamps then the 'shock' value goes completely. It'll be worse when all cars have daytime lights. If you want to be seen, be different - I've posted many times the comment by a mate after he followed me (in a BMW C1) on his Varadero (him, 21 stone on a big bike) "No-one saw me - they were all looking at you!"
Second, we are continually being told that lights & hi-viz is the way to go, from CBT onwards. Someone asked how such things were relevant to bikers? With the DSA's new register of post-test (ie 'advanced') trainers it will be mandatory to use hiviz & ligts during training. I was told by the DSA that it was 'best practice'.
You have asked for research; PM me an email addy and I'll send you a copy of some research in to police car conspicuity. Did you know that after they changed to the 'battenburg' scheme, more people drove in to them when they were parked?
no you didn't say but you did quote Shawover-estimated and under-estimated ie judged the speed inaccurately
Maybe because it's a broken-up design as opposed to a block of colour?
But I don't know much the estimates were wrong.
A vehicle with lights on make it harder to judge the speed of approach.
Good point - and think about the 'shell suit' designs applied to bikes and leathers over the years, classic 'disruptive' patterning . . If you've seen the battenburg crashes mentioned before, have you seen the 'battenburg tank' pics?
