No, but on Wednesday I think I was spotted.
I was riding into the setting sun along the A454 between Wolverhampton and Bridgnorth, when I heard a 'peep-peep' from car behind me, which then gave me the widest berth as it passed me. I think the driver waved as well. At first I though he must have mistaken me for someone else, but a more likely explanation was that he'd recognised my PBP gilet.
