The drivers a dickhead and I was secretly hoping they'd have a wheel ripped of by a hidden kerb or something and I hope they were at the very least arrested for that, but... well, let me come back to this thought.

Those cyclists are irresponsible pricks for riding in a pack like that. They look like they're trying to buy the own little Tour de France but that's clearly not a rally that was organised with cooperation of ANY relevant authority - council, highways, police, whatever - and just looks to me like a bunch of yuppies that decided to take over a highway. No pilot vehicles, no safety stewards, occupying the full width of both lanes for no reason other than that they can, just a rolling roadblock of self-righteousness and no consideration for other road users.

So, as I was saying: the drivers a dickhead and I was secretly hoping they'd have a wheel ripped of by a hidden kerb or something and I hope they were at the very least arrested for that, but... maybe they had a really, really good excuse for wanting - or needing - to get somewhere with desperate urgency and simply could not afford to be delayed at all, let alone by the arbitrary whims of a bunch of hobbyists. Or maybe everybody in the video was being a selfish-righteous prick.
