It was the passenger (foreigners do things on the wrong side) so it wasn't "his" door. Nor is he a moton, but only because he wasn't the motorist.
Am I the only one who saw the cars passing down the left of the camera car?
Nope, he said "typical moton", thus explicitly saying that it was typical behaviour for a moton and implying nothing about his thoughts on what constitutes normal behaviour for motorists.
IMO, if someone (driver or passenger) opens their door without checking behind, they are a moton. That says nothing of other people who drive or travel in cars, it says everything about that individual.
I doubt it was BM's clip, as it's abroad and filmed in a car.
No. I saw that too. That coupled with the number plates, tells me that the person who opened the door was the passenger, not the driver
