> One interesting way of reducing doorings is to teach drivers and passengers the Dutch reach. That really doesn't work. First, a cyclist is moving at least 15 feet per second, which is the average length of a passenger vehicle, so by the time they're besides you, they're already past you. Second, your view is blocked[1] by the B and C pillars of the vehicle as well as the headrest, so you won't be able to see a cyclist approaching. The second best approach is to check the outside mirror before opening the door, but that doesn't work for passengers in the vehicle. The absolute best approach is to never, ever, ride in the door zone, regardless of whether or not door zone bike lanes are present.
