Not all is perfect in paradise.
There you are, perfecly happy on the bike lane and suddenly you roll up behind one of the City's bike lane street sweepers and into a mini traffic jam. Bloody hell. What to do, what to do. You can either hop up onto the pavement and overtake or you can do what most people do, just roll along behind until he pulls over to let the cyclists past before continuing. Which he does regularly.
 

There you are, ready with your instruments to perform on the square for the passersby and a pesky 12 year old rolls up with his mum's Christiania bike and starts selling bottles of water. Although after a quick discussion, said 12 year old rolls 10 metres away and everyone is happy.
