It's known as filtering here because our roads in towns are still the same as the 60's basically but with more cars that are now coming more US in size over the years, so space is a premium , so filtering is squeezing to the front.
I have been a dispatch rider for nearly 30 years now, Bikes are used in cities because a delivery/ collection that would take a van to do in 30 + mins takes us less than 10 mins . It is not a case of speeding past lines of cars just getting past these daft buggers in these cages who are lined up traffic lights to traffic lights , more we ignore them and go to the front maintaining movement .Also we park outside our collection point for a few minutes where as vans need to find a loading bay.
On our motorways which are wider lanes it not a case of speed more momentum ....as the cars slow down or come to a stop we just move between and carry on the momentum......getting angry with the cars just gets yourself angry and making hasty descions .....most cars drivers here don't hinder you unless you ride like a tw*t. Audi's are an issue here aswell ....but they were in Germany aswell on out last trip ....ask Sparki! ( though the rest of the German drivers were appreciative )
Fun fact....Frank the Manc Yank used to be a dispatch rider here in Manchester until he moved to NYC to open a Candy store
