...Both Nutty and I often write about our findings regarding space and SMIDSYs when we stopped wearing HiVi.

I must get a photo of how I was garbed on one SMIDY. -> Hi-Viz orange long sleeved top with reflective stripes round arms and body. Sitting on a daffodil yellow motorbike with the lights on.
I've found over the years that adding hi-viz and/or helmet when cycling doesn't add much at all in the way of safety. If anything it decreased my safety as drivers cut me closer and pulled in earlier after overtaking.
I've posted before my fear re a cyclist on the A303 at night wearing black, but having followed him on my bike (with an accidental hi-viz moment as the most comfortable rain jacket happened to be yellow) I can vouch for the fact that he was just as visible as the rider next to him who was in hi-viz overload.
I now make a point of buying clothes for comfort, not colour. As I said above the rain jacket is hi-viz, but it was a close run thing between that and the black one. I will rarely wear a road worker's hi-viz vest over my clothing now as it's just too uncomfy and annoys me as it blows around in the wind.
And as I said to a person the other day who moaned that "cyclists" didn't wear hi-viz, "whose responsibility is it to go to each fallen tree on a road and put a hi-viz jacket on it so that drivers can see it instead of driving into it".
