I haven't seen anyone mentioning the Ian Walker study on drivers' responses to cyclists with and without helmets. https://www.sciencedirect.com/science/article

  I don't have access to the study, but wasn't it the one where: - the author was the only person studied - the difference wasn't that big ?

    That's the one. Due to its small size, it's more indicative of an effect - it would be interesting to see if it could be replicated. There's some bike cams (Garmin?) that include a radar to measure closeness of vehicles passing, so it would be relatively easy to conduct a much larger scale.
