I've been pondering on the greatest dangers to the urban biker:
- The street itself (border stones, I hate you)
- Road works
My bet is on the last point. All crashes and near-crashes I've had so fare were due to road works. My second bet is on the street itself - sometimes combined with cars. Usually cars that block the bikelane. They certainly make biking more of a hassle. I think for the next election, I'm rooting for the party that promises to provide a better biking infrastructure.
