Perhaps some things in bicycling are tough calls with imperfect
solutions. However, dooring is not one of them. Each individual
bicyclist has the 100% solution in their own hands - and each
bicyclist should take advantage of that 100% solution. Regardless
speed traffic typically flows in an area near parked cars when a
bicyclist is not present, bicyclists should ride outside all dooring
zones, all the time. As a matter of fact, in areas with higher typical
speeds, I choose roadway positions with a little _extra_ margin from
hazards rather than less. Probably, I would be a little extra left if
typical speeds along the roadway were higher (and I would be _a_lot_
more left if the increased speed I'm talking about is my own on the
bicycle - going down a hill for instance.)
Bicyclists need to assign themselves reasonable scanning duties.
Therefore they should not take on new and probably ineffective duties
(like studying the insides of each and every parked car ahead.) All
that attention and analysis is best redirected toward road surfaces
and intersection conditions ahead.
Also, when you ride fully outside the dooring zone you are in better
positioned to see and be seen - with respect to the edge-of-road-
obstacle parked cars represent. It's the right place to be for more
reasons than just dooring.
Sorry Zack. Disagree with your recommendations on this point.
We need to teach bicyclist to stop fearing overtaking traffic. This
misplaced fear leads to things like the culture missing the obvious
and easy 100% solution to the dooring issue. If the concern to stay
more right is only from dislike of creating perceived inconvenience to
overtaking traffic rather than fear of overtaking traffic... this
still represents a poor choice for balancing bicyclist _safety_
versus perceived overtaking traffic _convenience_.
