Jokes aside, I think it's important in situations like this to remain composed because they can quickly escalate. The moment you start name-calling (like that other guy appeared to do), it changes the dynamic..some people can turn violent very quickly. Then you have the police saying you escalated it somewhat by calling names and therefore they won't act..it happens. Maybe the guy stopped temporarily, we just don't know as the video doesn't show it. Nice car, though. Must have cost a bob or two.
Here is the original article where the video was featured http://www.dailymail.co.uk/news/article-4010056/Someone-call-911-Two-drivers-seen-having-furious-argument-one-parks-Porsche-middle-road-goes-shopping.html
It's the Daily Mail so it must be accurate hah
