If only that was always true: this[1] kind of lane is far too common. It's completely counter-productive as it actually encourages the cyclist into the door zone without being wide enough to keep passing traffic at a safe distance (also a dashed-line means cars may enter the lane anyway, so it's indicative only).
The safest place to cycle here is probably so far right that a car won't be able to pass without a full overtake in the oncoming lane, moving to the left only when there are no door hazards. also you should keep right though the choke-point island, as you do not want a car to overtake you there, unless you want a taste of one of those bollards - imagine being a bike next to the black oncoming car.
However, such an assertive riding position tends to upset cars who may instead punishment-pass the cyclist. Understandably, many cyclists prefer not to open themselves to such bullying and will instead stick to their lanes, and risk doorings instead.
Even quite wide, well-marked and "safe-looking" lanes can still be mostly within the door zone[2].
