This is so frightfully un-Danish and certainly not representative of what we do here. But wackos are all over the place.
A Danish 'cycling enthusiast' went nuts and chased after a bus that he felt passed him too close while it was avoiding oncoming traffic. The 'cyclist' followed the bus to the end station outside of Aarhus and then boarded it to begin beating the bus chaffeur, leaving him badly cut and bruised.
The man was caught on the busses camera and it took two weeks for the police to apprehend him, but they did so in the end. Not really a great advert for Team CSC - now Saxobank.
