I am a little concerned about the way this is report. The study is based on personal experiences, which are inevitably based on perception.
In the Guardian, it says
"Female cyclists are almost twice as likely as their male counterparts to be subjected to harassment or bad driving, according to a study that describes such frightening events as an everyday experience for most UK cyclists."
I don't think that this can be concluded directly. Below it says:
"On average, women reported about 0.42 “near miss” or harassment incidents per mile, compared with 0.24 per mile for men."
One might think that there might different levels of reporting, sensitivity or perception between different types of people, including between sexes.
However the overall levels of reporting are high and bring home the message that it's not just about how safe routes are in terms of casualties stats but how safe they are perceived to be. And the detrimental effect of poor driving on cycle commuting.
