I think you’re aiming at the wrong audience on here – we’re an obvious majority that wouldn’t think we needed additional training, after all, we’re all very good riders (aren’t we…?)
I also reckon that what would perhaps work better, if you’re after people to consider more training would be a more structured questionnaire that highlighted some of the areas that ‘casual’ riders would be more concerned about, e.g. their safety, riding defensively etc. At present, you’re asking Y/N questions which are clearly written by someone who knows cycling, which is useful for fact gathering, but not identifying areas which people would like to address. And there’s no lead into how cycle instruction could help, as again it’s a Y/N.
Could you get a website up and running or something, with a more exploratory questionnaire, and supporting info, and then get posters in your local leisure centres, bikeshops etc? Different audience completely then.
