Collision types 5, 6, 7 all seem predicated on the unwritten assumption that you're in an impromptu lane (one lane, two vehicles) with a car. In that case, yeah, it's always a bad idea. But where the collisions happen, in my experience, is the following setup: /---------> | +---+ | | +----------------- | | | | | | |car| | B | Right | | | | | turn | | +---+ | | only | | | | From left to right, there are three lanes: Leftmost, a straight-travel lane, with a car, in the middle lane, a dedicated bike lane with a biker, and on the far right, a right turn lane for cars. Here, the car, in the third lane from the right hand side of the road, proceeds to turn right, and clips a biker in the process. I have seen this near-hit so many times, that in my car we have a designated phrasing for it ("right turn from not the rightmost lane"), and it is, to me, the most dangerous thing out there, in turns of commonness (frighteningly common) and severity (very collision prone). (Vs. something like "driving the wrong way", which while highly dangerous, doesn't tend to happen as often, relative to this.) Happens even when the bike lane isn't a thing, in car-on-car scenarios too. Of the three collisions I've seen cyclists in, two were this setup. (Both cyclists walked away, thankfully; the last collision I've witness was a dooring.) The nearest-to-death I've ever been on a bike was this setup, except the turning car was in lane 1, on a 5 lane road. I.e., he turned right, from the left turn only lane, across 4 lanes of traffic, and nearly hit me in the process. I was forced to take the right (basically along his side) in order to avoid the collision. His words: "sorry." On dooring, > Ride to the left. Ride far enough to the left that you won't run into any door that's opened unexpectedly. Where I am we have dedicated bike lanes. To ride left enough to avoid a door would require me to abandon the bike lane, as it isn't wide enough for a door and a bike.
