This video is really unfortunate and gives all motorcyclists a bad name - the type of bike you ride has nothing to do with it. I've seen guys on Harleys act like maniacs, and guys on sportbikes act like thugs. It's too bad. The majority of motorcyclists I know are careful, respectful of other drivers and of the machine, and don't break laws.

All parties in this video acted irresponsibly. This is not how you conduct a group ride. And you don't risk your life to "tell off" the driver of a car acting aggressively. 

In motorcycling, a cool head lives the longest.
