There's a behavourial campaign at the moment with car doors placed around town and the message "Catch the cyclist with your eyes, not your door".

Pretty straightforward campaign. No real fear-mongering at play. Just a good reminder for both motorists and cyclists alike. Nevermind the fact that I have never heard of anybody getting smacked by a car door. Most of the bike lanes are wide enough to avoid this. But hey. At least the campaign helps motorists [most of whom are cyclists, too] remember the bicycles.

Thanks to Kristoffer for the photo.
