No, it is the fear of these all too powerful anti-discrimination laws. You see in the video how someone gets punched in the chest but doesn't dare fight back or even chase after the bikers in the store. Even the store employees are afraid to stop the bicyclists.

Because of these laws, these criminals feel they have IMPUNITY. That's why they can crash into cars and accuse the driver of being the one at fault. They know the anti-racism activist lawyers will go to work for them FOR FREE due to the anti-racism and social welfare legal support.

The stimulus for the bad behaviour are the black dudes with the youtube channel seeking subscribers. The black dude is also building up street cred with the other blacks. Such channels attract other "hangers on" and "wannabees" which might not be black, but are influenced by the bad behaviour of the feral blacks. 

This is a common problem in the USA too where feral blacks influence white women and indoctrinate them into bad behavior and single motherhood.
