When I lived in Italy the choice of mode of transportation and whether to use the highway when driving was dependent on the number of occupants. Choices, ordered by price ascending were: 1 person - train, backroads, highway 2 people - backroads, train, highway 3 people - backroads, highway, train Also train was faster than backroads, but slower than highway. Nevertheless with 2 people on board I often opted for the backroads, because then we could leave at e.g. 10pm after a long supper.
