Did I miss something when the above link was posted at the start of the thread?
I posted a new thread without seeing this one, must have been merged.
Lighting - we know how the brain judges the speed of an oncoming vehicle by the rate at which it gets apparently bigger in relation to its surroundings. So far so good.is it the motion camouflage phenonomomonon?

This is why headlights during the day are bad - they break up the outline of the image, making it impossible to judge the speed. Proper low wattage day running lights are much safer.
Motorcyclists have had this foisted on the by Europe and modern bikes gave their dipped beam permanently on. Keep an eye out on motorbikes and eventually you will se that you can spot the headlight, but often not the bike and rider behind it until its almost on top of you.
All the bike manufacturers fought this, including Honda who own a major search light manufacturer so have world leading expertise in the science of optics. They argued for lower wattage lighting spaced apart, such as at bar ends or maybe with a theirs on the front mudguard to form a triangle. This makes the bike conspicuous, but aids soeed calculation as the onlookers brain had a ready reference as the lights apparently get further apart ad the bike gets nearer.
But no, the unelected Eurocrats decided daytime headlights were the way forward, despite there being zero evidence they are effective in anything other than sub-arctic climates.
It's the fluorescent wearing safety without logic culture gone mad.

Well, I was taught about this when I was learning to drive back in the early 80's. Didn't even know it had a name then but I was taught to counter it by looking properly.

My dad was a war time pilot in an artillery spotter plane. If there's one pilot who needs to see everything it was those guys. Cruising around at less than a quarter of the speed of a Messerschmitt 109, within small arms ground fire range and returning to base over 'friendly' shell fire, looking out for pylons and cables, good observation was crucial. When he taught me to drive he made darned sure I looked and looked. As he had done in wartime he also made me keep the windscreen and mirrors spotless. All useful stuff..
