I must be honest - all three looked relatively innocuous to me.
My camera's microphone is awful, so please do increase the volume of your viewing device, it's a low volume which my camera produces. It's also in a waterproof case. My helmet camera distorts the impression of distance. I would use the camera distortion removal feature, but then the view becomes very narrow. Hope I'm not presuming, but our two eyes see far wider and clearer, have far superior dynamic range, than any action camera. In the videos, driver's faces are not visible, but I could clearly see where driver's were looking - I've found that looking driver's in the eye is a good way to guage what they are actually looking at, and whether they have noticed me, sadly faces and eyes aren't visible in the video my camera produces, the human eye is far superior. It makes me question the usefulness of my helmet camera's "Flight recorder" function, should something horrible happen and I need evidence. I might experiment, setting to remove distortion automatically in-camera in future.
First one you could see the slightly open door from some considerable distance, and the guy obviously saw you as well.
If there was no distortion, perception of distances would be more accurate. I could clearly see their faces. The chap opening the door didn't see me at all, neither did his companion, and it was only after I beeped that he noticed, and started to close his door. I would have been forced to swerve further to the right if he hadn't, which risked possible collision with vehicles overtaking.
Second one the car was only gently starting to pull out and then immediately stopped when he realised you were turning right.
Did you hear his angry tyre squeal, as he pulled away afterwards? You might have to turn up the volume and use headphones to hear it, and engine noises. The young Caribbean driver looked angry. The driver and his friend looked like they were having a great conversation as they pulled up to the intersection, the driver didn't look in my direction at all until I beeped, too busy chatting to his mate, and even then he moved to cross right in front of me. I had right of way. If I was in a car, he would have waited for me to turn right, because I would have been blocked his way. There appears to be a blind spot or something: Drivers don't see bikes at about 30 to 45 degrees either side, after stopping to turn - they look at fully 90 degrees left or right, but miss seeing bikes situated (or have moved to) slightly further toward the middle, for some reason. I'm sure cars would be more visible in the same situation, as they are larger and occupy more of the driver's field of view. Plus drivers don't often see bikes anyway, because they mostly expect to see cars. I've frequently seen drivers screech to a stop, when they suddenly see a bike move out of that blind spot. A driver who did that the other night actually swore "F&king hell!" as he suddenly saw me and slammed on the brakes after accelerating at me, while turning onto the main road I was travelling along - he didn't even look to his right, which worried me, didn't slow down much and wasn't going to actually stop before turning into ther main road from the side road to my left. I had slowed down and was wondering whether to beep to alert him to my prescence, and I should have but didn't - I hate beeping, seems rude and should be unnecessary, especially in that situation, when he should have looked right at least once. He slammed on his brakes when I was directly in front of him, having moved out of that blind spot, which shouldn't be a blind spot, or wouldn't be a blind spot if I were driving a car. The video of that was too dark, or I would have included it. No helmet camera seems any good at night.
Third one - sorry, but I didn't detect any actual attempt at overtaking, just two cars quite close to each other, and in line.
That one was utterly terrifying. If you turn the volume up or use headphones, you can hear his tyres screech as hie rapidly alters trajectory (about 38s into the video). If he hadn't rapidly changed course, I'd have been toast. He actually ducked to avoid my horrified gaze as he passed, looked sheepish. I was a "Deer in headlights", and would have been squished or airborne.
I totally understand if my camera recordings don't accurately show what occurred, and that you don't see what I saw and heard. If I only saw these videos and wasn't there, I might be of the same opinion as you, possibly. At least my helmet camera picks up number plates, which may be of use in a hit and run situation.
