To me it seem dangerous to drive in the middle of "heavy" traffic, but you actually have to do that too on what we call 45 km/h mopeds, witch is regarded like a Little MC but can be driven from you are 18 and have a licence for car or MC.
Those 45 km/h mopeds in mid traffic witch at times move at 70 - 80 km/h is just asking for truble in my eyes, but they are not allowed on bicycle paths where 30 km/h mopeds are allowed and supposed to drive. ( if there is one otherwise its keep right on the street and dont drive side by side as that take up too much room )
And those 45 mopeds are slower than what is allowed to be driven by kids 16 up in most other EU countries, but us stupid Danes have to be so damm special.
At times you will see ppl on bicycle move from the far right curbe across 2 or more lanes to get into the L turn lane, again somthing witch is not allowed here.
To make a L turn at a intersection here you have to go strait across the intersection, then wait at the cornor there untill the crossing traffic get green light or there is a hole in the traffic.
The only thing cyclists here more or less have in common with the motorized traffic is the rules ( light of color ) in interserctions, they are in general called "Soft motorists"
