I don't understand the relevance of your link to this story or even Thailand. You have taken this thread widely off the topic. Talking about your crazy ex and all kinds of things that have nothing to do with anything. Now some strange link that again has no relevance to the story. Have you been to Pattaya?
If not, why are you telling people that if they haven't lived in the U.S. ...? You haven't been to Pattaya either.
The Brit could likely have easily have avoided the situation. A car cannot keep up with a motorcycle on that soi, so probably he decided to stay and confront.
