As I recall, in one large city doorings comprised about 20% of fatal/severe bicycle crashes. Unfortunately, MVUCC guidelines can leave out dooring crashes as the motor vehicle is typically parked and isn't "in transit".
With window tint and mandatory headrests, it can be very difficult to assess occupancy of a motor vehicle. And a car or truck door can go from closed to fully open in half a second. I try to generally presume that any door can suddenly open in my path, and wherever practicable ride about 5 feet away from the parked vehicle, regardless of pavement markings. If you're not in the swept path of the door, it's a lot easier to avoid that collision.
