The emphasis on "if." How exactly is it in any way safer? That is what I'm getting at. If somebody can point out how driving with your lights on in broad daylight is safer than not doing so, then I'll gladly flick my beams on during the day - sure thing. To date, nobody has been able to answer how it is in any way safer. The sheeple heard it on radio, assumed it
must be safer and went ahead with it without ever questioning why (which we know you like to do w1z4rd

)
So...how is it in any way safer?
As far as I understand it, there is a few things to keep in mind. Your brain functions on differences, not constants. For example, we have a fridge fairly close to the TV room. I never hear the sound of the fridge unless something changes, if it switches off or something like that. Your brain filters out the constant, so in the case of vehicles, even though your brain filters out the colour, it should pick up the difference from the lights.
Secondly the closer the colour of your car is to the colour of the tarmac / road / whatever, the more difficult it is for your brain to pick up. Again the fact of switching on the lights might make a major difference.
And yes, of course everybody of us is a brilliant driver and never gets distracted and never makes a mistake. But for that one person that might be a bit distracted, that might not be focusing like they should, this could make a major difference, I might even go as far as to say it might be the difference between staying alive and, well not.
The fact of the matter, in my view, is that it is such a small thing, and even if it only makes a difference in 0.00000001% of the cases, it might still save the life of somebody, it might even be you.
So viewed in that matter, is it really such a bad thing?
And that excludes the studies done proving that driving with your lights on is safer. Sure, most of these might be done in European countries or the like, where visibility might be very different from here. But personally I think that especially your dark coloured cars, especially that grey / silver / metallic ones can really do with making themselves more visible.
So yes; do as you choose.
I personally drive with my lights on all the time.
I also drive with my seat belt on and I don't answer my cellphone while driving.
But this might just be me, or it might be that I won't be able to tell the loved one of somebody that I just crashed into that I couldn't be bothered to switch on my lights, or that I felt that my phone call was more important than the live just lost.
