We didn't drive from Oslo to Bergen. We drove some 2 km from our home to a parking place by the forest border. Then we took the metro to the other side of Oslo and started our skiing journey there :-)

Bergen is not that far north, it's probably the same latitude as Oslo, maybe a little bit further north. I would believe the urban areas of Bergen is free of snow now, but there are lots of mountains around Bergen, even close to downtown.
