The only thing I disagree with is the use of the term "biker"... Not everyone who rides a motorcycle is a biker.. Those guys certainly aren't.
At best they are "motorcyclists" at worst they ae a street gang.. It's not the first time they have done this sort of thing either.
ALL of my friends are bikers, I have spent 30+ years riding bikes and have been a biker for 20+ of those.
The distinction is subtle to non-riders (and to be fair to "motorcyclists" too).
Not all motorcyclists are bad people, most of them are thoroughly decent people, most bikers are lovely once you get to know them too.
The guys in the video give all road users a bad name, it's a shame they chose motorcycles as their method of transport.
It's just as well it wasn't texas, or Arizona I guess otherwise there would no doubt have been a shootout too..
