I've always thought that the worst drivers in Sweden are the ones from #Skåne, but today I had a dark green VW Amarok that drove all the way from Falkenberg in #Halland to beyond Halmstad on the E6 and never ever did he fall back in to the right hand lane. He stayed in the left lane on the motorway no matter what was in (or wasn't) in the right hand lane!
When you are doing 120 km/h, and above (he was mostly above), you should go back into the right hand lane when you are done with overtaking.
