You do know that single file isn't required? And how would you safely pass a long row of them?
Like a lot of other road users that aren't cars, cycles have characteristics that car drivers simply have to accept. As I've said before, many road users are temperamentally unsuited to what they are doing.
Required in who's eyes ?
The lycra clad idiot who drives through red lights on a regular basis ?
The lycra clad idiot who rides on the pavement when it suits him ?
The lycra clad w@nker that nearly ran me and the dog over this morning while on a zebra crossing after 2 lanes of traffic stopped and he couldn't be arsed to ?
He did have a very nice camera bolted to the top of his helmet though which would have been used to prosecute me for smashing fook out of him if he would have had the balls to stop instead of riding off laughing
Matt is spot on with his opinion of motor vehicles passing too close to push bikes BUT to say that just because the law states that a cycle doesn't have to travel in single file then its okay to do what the fook you like is 'dangle berries'.
Its about time cyclists remembered that they are vulnerable and should take more care to avoid accidents, rather then deliberately holding up other traffic just because they can
The roads are plenty big enough for all modes of transport IF everybody took a little time to use that road in a safe, respectful and courteous manner
So you tell me, what is the real problem here ?
I have never said it's OK to do whatever you like. But cyclists riding in single file or blocks is often a case of choosing the least bad option. Pulling over is only advisable when it is safe to do so. On a narrow, busy or even fast moving road taking charge of the traffic is what any road user who has had instruction is specifically taught to to do. You do it in a car. A cyclist riding in the middle of his lane due to bad conditions(which could be the road surface, traffic, whatever) is no different to a truck driver swinging out early to make a tight turn: it is to reduce the need to explain, and figure out who is going to pay for, the 'accident'.
I've explained the real problem many times: many people who use the roads are aggressive, incompetent, incapable, unaware of their surroundings, day dreaming, on the phone, lost, not looking or thinking what they are doing, and think that the laws and adopted best practice don't apply to them. That's just what people are like; there's nothing to be done about it.
Fair enough Nick

A little bit over the top on my part maybe

Probably due to the prick on the crossing nearly hitting me my dog then riding off laughing his tiny cock off

Bastard

Imho, that highlighted lot basically sums up the majority of those who have turned to lycra (cos its the "In" thing to do)
Obviously things need to change here and daft videos and even more persecution by the police isn't going to change a thing imo.
From what you have said on here, your not one of the lycra w@nkers who weave in and out of traffic, ride on the pavement or believe traffic laws don't apply to you so a question for you if I may ?
What needs to be done / how do we stop these oppswits who ride there bikes like this and give the sensible push bike riders a bad name ?
Bearing in mind, a motor vehicle owner / driver need to pass a test, maintain his vehicle to a reasonably standard, and have liability insurance before he can even use the public highway.
How can the playing field be made more level ?
