This. I was doored twice, many years ago. Both time I could not see that there was anybody in the car. One was at night, parked below a streetlight with no lights on in the car. The other was a woman looking for her kid's toy on the floor before opening the door. Both times I was tossed into the middle of the car lane. If you think about it, a car door is a device designed to toss objects weighing 100 to several hundred pounds away from the car at most of the speed that object was traveling prior to. THe car door doesn't kill you. The vehicle behind you just might. (There was a tread on this where the truck driver was driving illegally. The thread went on for pages before someone pointed out that his driving status had zero to do with this death. The best driver in the world would have been in the same boat unless he choose to stay well behind the cyclist until the road was clear of parked cars. In some cities, that doesn't happen and driving that slow would irritate many drivers.

On You Tube there are videos showing jut how far away from a car you need to be to avoid being hit by an opening door. It's quite a distance and more so if the car is a two door because the doors are longer than a four door. Trucks, pickup or others, often have bigger doors.

In traffic I will not ride in the door zone even if it's a bicycle lane. Why? Because if someone opens a driver side door when I'm directly opposit them I'd be deflected into traffic or under some vehicle's wheels. It's simply not worth the risk to me.
Headrests on automobile seats and a driver of small staure can make it impossible to see that driver as you approach the vehicle. Add in tinted rear and side windows (not the driver's) and it's even harder to tell if someone is in the driver's seat. Or if the driver is leaning down and opens the door.
YMMV and apparently does but my advice is to simply avoid riding in the door zone.

No, I saw that. I've seen people on bicycle gets doored and the result of getting doored is not pretty. Therefore I don't ride in any door zone. My outlook is that it's possible to avoid riding in the door zone. For me it is NOT unavoidable to ride in a door zone. Why some people persist in riding in the door zone is beyond me. I also don't understand why so many so called bicycle lanes are painted/created that put bicyclists in the door zone.
Ride in the door zone if you like but know that it's very risky thing to do.
Edit. Here are a couple of videos that show just how far from a car door a bicyclist needs to be to be safe from an opening door. Start at the 1:25 point of this video.
About the 1:00 point in this video.

I'm with Miele Man on this one.
The problem with the door zone is unlike most cycling where a little courtesy and defensive riding can go a long way to reduce the risk of accidents for cyclists, Riding in the door zone is a crap shoot. It's not a matter of if, It's a matter of when if you ride there frequently. That's why I either avoid a busy narrow route with parked cars even if it adds a few minutes to my ride, Or stay far out of the door zone. If we can't do either, SLOW DOWN.
That anti-dooring feature is great for the owner of the car, But the tiny percentage of cars that might have it in 5 - 10 years does little for us cyclist.
As for those bike/door zone lanes with parked cars may actually be worse then no markings at all as it implies a false sense of security.

Maybe worrywart cyclists should worry less about the door zone because it really isn't doing them any good. American cyclist metrics for negative interactions with motor vehicles are the worst in the developed world. All this fear, all this helmet adoption, all this obsession with lights and horns and and ... what? Why don't we have the best safety metrics? Maybe you should listen to us gutter hugging, door zone bike lane adopting, Idaho stopping, rational cyclists ...

Ought to be capable of having 180-degree visible turn signals mounted to the side-view mirror assemblies, radar/lidar sensors to know when fast-approaching vehicles or others are in the "danger zone," and ought to be able to loudly and clearly inform a driver/passenger that there's an apparent extreme risks of opening the door right then. Won't be perfect, probably, but it's better than the "wing-it" method most folks employ now.
My own car's about ten years old, and on the sides it's only got the proximity warning lights (for the driver) associated with the side-view mirrors (blind spot monitoring). No turn-signal lighting on the mirrors, and certainly no rear-facing blind spot monitoring as would be necessary for a bike lane. Hopefully it'll come, at some point.

But the nice thing is, as such capabilities get put into puny chips and made ubiquitous, it'll be hard to get away from such things in a few years. Most (if not all) "basic" new cars might well be coming with such stuff integrated into the "base" package. Personal vehicles might well become all but unobtainable for the average person, other than on the pre-owned market. But, still. Nice features. IMO, it won't be too long before most makers are putting such stuff into most models.

Now if they'd make the rest of the door safe...
