It is arguable the 22% caused by open car doors is also negligence on the cyclist's part. Riding that fast and that close to doors that may or may not suddenly open without warning is negligent. It would be akin to a lane-splitting motorcyclist failing to anticipate someone might change lanes without warning during heavy traffic.
disagree. the most typical bike lane in America is nicknamed "dooring lane" - a painted lane that forces cyclists to ride in the dooring zone. As for speed, I've been stopped at a light and had a parked driver open their door into me without even looking. If riding next to parked cars is dangerous, then it's the street designers who are to blame.
To ride out of the door zone in many cases requires taking the lane and riding outside of a marked bicycle lane, if present. Cyclists can and should do this, but it is no surprise that many don’t, and it is no surprise that drivers complain of those who do.
