   Yes, I understood that, but where does the expressions come from, how   
   did they originate?   
      
   AFAIK, both are prohibited here. Maybe Lane filtering is permitted (it   
   certainly happens), but there is still a risk of a car opening a door.   
   There is another variant that was permitted recently, which is a bike   
   slowly driving on the shoulder during a traffic jam, but still yielding   
   to emergency vehicles using the shoulder.
