It's weird to see this described as a workaround, or a deliberate method, when to me as a swede living in Malmö it's the most natural thing ever.
It's up to drivers, and cab drivers, to warn their passengers to be careful when opening the door. Of course this is an imperfect system but from my perspective it has worked for as long as I've lived.
Swedish traffic law dictates that the one opening the door is responsible for any damages caused, so to protect themselves, their insurance premium and their cars drivers obviously become careful when opening doors.
It messes up your whole daily routine if your door is broken because of a bicycle.
