Please post a warning of where these signs are displayed so we can all avoid them:w00t:
Notice the lane is empty because bmw riders are such advanced and excellent riders that they will usually only filter their aluminium boxes to the offside of the traffic where they can cause maximum blockage to the passage of all other inferior motorcyclists.
Sorry, we thought it referred to BMW cars 
could that be the oxford ring road:)
Ah come on play nice! Some If us are progressive
Riders!!
