pack of fucking dickhead bike enthusiasts riding around your vehicle in your blind spots and in close proximity so you don't even know where they are and if you can change lanes ect.

You mean the truck that deliberately slowed down to drive the same speed as the bikers to harass them?

Of course like anyone when they get on a bike they think because they have a full field of view around them that every other vehicle must has as well.

That's a pretty poor generalization.

And that's exactly what they were doing. Riding all around his truck like a swarm of flies.

There was one bike in front of the truck, the rest were on the left. Hardly "surrounded".

He even mentions that he's a bike rider himself and they were riding like idiots and that's why he was pissed.

I severely doubt the dickhead was a biker himself. With all of his actions and manner towards everyone.

I'm not surprised the gun came out when you started knocking on the other window too. You effectively surrounded his vehicle and started banging on it.

While not the BEST option for OP, I think most can agree. The truck still isn't "surrounded" and OP wasn't "banging" on the truck either.

It was an aggressive move from a bunch of guys riding aggressively in the first place.

Only aggression in the video is the dickhead truck driver and his buddies harassing the group of riders who are trying to mind their own business with verbal and physical gestures.

I don't condone the gun waving, but wow guys, learn to ride and not to intimidate people when you're in a large group.

The biker group did nothing to "intimidate" the truck. The truck was the one "intimidating" the group of bikes.

You're all temporary citizens riding like that. I hope you've all got a funeral plan because it's only a matter of time before someone who hasn't seen you at all just merges on you.

Except for the truck driver who was hanging out the window screaming obscenities at the bikers right? Yeah, he TOTALLY didn't see them. Not at all. /s
