I've been driving the Thai roads for over 20 years
When driving I don't pay too much attention to the white lines, I give way to all traffic, everyone has right of way. It takes me a little longer to get from A to B and spend a little more on fuel and brake pads.
I reckon most are missing the point, seriously, on this road you are just not expecting ANYTHING, car, truck, bus or scooter to come flying out of the roads east/west.
Once I saw the video I think page 2 or 3, I made a comment, it's one of the strangest things I've ever seen on Thailand's roads, probably won't see something as stupid again.
Yes, the SUV maybe in the wrong but to be fair, you are just not expecting this situation, that little scooter, barely visible, at speed flying through that very, very dangerous intersection is not normal driving behaviour and a rare sight.
I reckon most of us here, if we were driving the SUV at the time, would have driven into the Swiss guy, an unavoidable accident.
Makes me wonder if the Swiss guy sat back waiting for a come driving at speed, I'm thinking he was looking for an accident.
