The Wharf account of the incident can be read here; The New York Times also has an account here which includes a video taken from a security camera. One of the riders in the group, also has a couple of Flickr photos here.
This incident is such a freaky one that it's difficult to draw "lessons" from it, but here at least are a few observations (feel free to chime in if you have others):
- The danger here is by no means confined to cyclists; pedestrians or motorists would have been equally at risk;
- The truck driver was clearly negligent (in not buttoning-up his truck at the very least) and deserves a healthy fine;
- The system of sidewalk/curb/bike lane/parking lane/driving lane would have greatly ameliorated (if not eliminated) the risk here;
- Boris Johnson is one lucky guy, as are his fellow riders;
