Probably some due to the safety features, but I think its wrong to focus on Telsa alone here - modern cars (such as Tesla) have much better safety features than the cars from the 1970s. Norway has a high standard of living, and there are a lot of nice and new cars in Oslo.
Most of this is probably due to the local government focus on walkability. The article describes that the reduction is due to reduced speed limits, an increased amount of bike-paths and limiting a large number of roads to only pedestrian traffic. The large increase in road tolls and increase in cycling has probably also reduced the total number of cars on the road.
Anecdotally I've got the impression that Tesla drivers are among the most aggressive ones on the road in Norway, but this is only my experience.
