I can't get past the OP's ridiculous behavior in the video. He's taking a dog on a leash into a bike lane on a street and riding his ebike fairly fast. So basically, he's limited his own ability to adapt his path around any obstacle in the bike lane without causing the leashed dog to go into the traffic lane. The driver didn't "fling" the door open, caught the mistake before any harm was actually done, and then the OP proceeds to throw a tantrum.

I think dooring is probably the most exaggerated hazard of riding, and I find in urban riding I am generally able to ride a bit further to the left when going fast to avoid the hazard, and if I'm going slow, there's generally plenty of notice that the door is opening.

Bike lanes are for biking, not dog walking. I see no reason for cycling advocates to ignore that just because the dog walker is on a bike.
