My question as well. The next sentence says: "In the long term, the truck will also run between Gothenburg and the city of Borås, 70 km from Gothenburg."

So the implication is that it's not being used for that distance yet.

70km is really not very far. Great if you can take some short haul diesels off the road I guess, but that's not even a 1-hr drive on most roads.
