I saw the 'pedal bus' passing through Southwark the other week. This is an odd contraption for several people where you sit facing other riders opposite, all pedalling and moving forwards. Looked like great fun to try.
Anyway, as it was stuck at some lights, a motorcyclist came up behind it, revving his engine loudly as there was no room to pass. When the lights changed, he roared past at high speed and pulled a wheelie before shooting off down the road. He obviously didn't like getting stuck behind the pedibike and made his opinion known by pulling the wheelie. I just thought he was being an impatient dick as there was no need for it.
Why do some bikers ride machines that are so loud?. Surely they must contravene noise laws?. After seeing this penis-on-a-motorbike, I was reminded of an episode of South Park where the kids have there peace and quiet spoilt by a motorbike gang who ride around town but are disappointed that no-one pays attention to them and their excessively loud bikes (it's the one where Cartman tries to have bikers defined in law as 'gay').
