The only outfit associated with a significant change in mean passing proximities was the **police/video-recording jacket. **
Notably, whilst some outfits seemed to discourage motorists from passing within 1 metre of the rider, approximately 1-2% of overtakes came within 50 cm no matter what outfit was worn. This suggests there is little riders can do, by altering their appearance, to prevent the very closest overtakes
This is quite discouraging, but it seems to ring true in my experience. I’ve had quite a few drivers, who have come close to hitting me (even while walking at a crosswalk), claim that they “didn’t see me” while I wore high-viz everything and had lights to further improve visibility.
How do we, as cyclists, even deal with “driver blindness”?
My favourite in town separation is the series:
My real favourite in town is the roads that keep traffic at cycle speed, or better yet gives more direct paths for pedestrians and cyclists and circuitous paths for cars
