They were both unreasonable.
Regardless of who had the right of way, that situation should not have taken 35 minutes to resolve. One of them should have reversed for the sake of the other people waiting, if nothing else.
That should have been the priority long before the 35 minutes of that video were over. Not who had the right of way but who was prepared to let that 'right' go and just move for the sake of everybody else.
However I have just as much sympathy for her as for him if it comes down to feeling under pressure and frightened.
I understand they were both stressed and under pressure from the situation, and yes the woman possibly could more easily have resolved that because she didn't appear to lose her driving ability. The fact that he did means he's not really safe to be driving at all.
Obviously nobody was filming the start of that stand-off, so we don't know how long it took for the man to become incapable of driving safely or why. She might not have said a word to him, just sat and waited for him to reverse as she believed he should.
I don't know if he thought he was in the right, or if he just lost his nerve right from the moment the impasse started. But he was waiting just as long as she was, without even half of the abuse that she received. He was waiting for her just as long as she was waiting for him before the other people got involved.
I had to put the sound off on the video because I'm not in a place where I wanted that language to be heard, and I'm half-deaf so I need the sound right up, but from what I heard of the other drivers before I put the sound off, in particular the man in the high-viz jacket, she bore the brunt of all the insults and swearing while he was called mate and was spoken to with some concern.
Perhaps that's just the bit I heard but the high-viz man swore at her and called him mate, so the treatment of both drivers by one particular person seems very different to me and her car was definitely more surrounded than his.
Just because she wasn't showing stress and fear in the same way as he did, doesn't mean she wasn't feeling it though. Having a crowd of men line up the length of your open car to shout and swear at you, no matter what the circumstances were which brought them there, must be a frightening experience and I think I'd be quite shaken by it when it came to drive away.
Sometimes picking your battles is more important than being right. Everyone on that road would have been better off if one or the other of the two drivers had thought that way in this situation right at the start.
As for whether the by-standers would have leaned in and shouted at another man, I was a passenger in DH's car recently, traveling on a long two lane carriageway.
Another car was weaving from lane to lane to try and get ahead and almost hit the side of DH's car. I don't think he'd even realised we were there. DH sounded the horn to warn him and braked, the other driver swerved back into his own lane and thankfully he missed us by inches.
Then we stopped at a set of red lights almost right next to him, him on the left to turn left, us on the right to go straight on. And his passenger got out, ran over to our car and called me (the passenger) a fucking bitch and tried to spit on me through the open window. He also tried to open my door. Then, as DH started to open his own door, he ran back to his friends car, got back in and they drove off. The driver looked just as shocked as we were to be honest.
He, that male passenger, obviously thought we were to blame for some reason, but he didn't pick on DH who is quite big and fit and a man and who was actually driving the car he took issue with. Instead he attacked me, and I'm small, and not fit, and a woman, and I wasn't even driving.
I'm still quite shaken up by that, and bloody angry about it as well.
So I'm also inclined to think that if it were two male drivers in this impasse it might have been very different when it came to how the by-standers were treating them.
