Some people here find a racial angle in everything. I would say Thailand is one of the countries in the world with the lowest amount of road rage, and here you are blaming Thai culture and society for one guy's bad behavior based on a dashcam video. My response would be, if society here is as awful as you say, then why is it "psychotic" to be angry about it? Second of all, if you want to see a sick society, I can show you many videos like this from the fake democracy in America, where everyone seems to be currently angry as hell about almost everything. There, instead of cutting off ambulances, they shoot at each other or get out and fight in the streets or other wild malicious acts.
