Vehicles Pass Closer to Helmeted Cyclists

Here’s a subject close to my
heart: cycling. Not least because I’m a keen cyclist myself but also because
cycling is good in so many different ways – but I’m not going to bang on about
that now. This study, however, has some counter-intuitive findings (the best
kind!) about helmet wearing that seems to suggest cars pass closer if you’ve
got a lid on. Also, and in stark contrast to conventional wisdom among
experienced cyclists, riding further away from the curb does not cause road
users to leave more space when over-taking.
Here’s the suggested
explanation for the ‘helmet-effect’:
“Research suggests drivers
tend to believe helmeted cyclists are more serious and less likely to make
unexpected moves; the helmet effect seen here is likely a behavioural
manifestation of this belief.”
And on the riding position:
“The riding-position effect
suggests drivers simply do not change their overtaking paths very much as a
function of where a rider is: if a cyclist rides further into the road, they
will on average be closer to passing vehicles as a result. However, there are
also plenty of reasons why riders should not just stick to the road edge, e.g.,
debris, car doors, and drivers’ attention patterns at junctions.”
Oh, and when the experimenter
wore a wig, it seemed to have a repellent effect on other road users. That, I’m
less surprised about.
