When I cycle, I wear a high-visibility waistcoat. It’s basically a piece of fluorescent yellow fabric with reflective bands that drapes over my shoulders and rucksack.
Unfortunately, it’s just as vulnerable to the hi-vis effect as my green-yoked medical hi-vis jacket.
So far, today, I’ve been asked directions in the train station (twice), asked to break up a fight (and caused a massive tut of disgust when I pointed walked the other way) and a car pulled over to be directed to the train station.
On the bright side, I also got a discount on my dinner, and waved through the train turnstile ahead of a crowd (yes, I had a ticket!).
Sometimes the effect isn’t all that bad.
