The roads around here (Helsinki, Finland) used to be congested by trailer trucks transporting new Japanese cars from the harbour in Hanko across border to St. Petersburg.
Bothered by the flow of trucks, I asked why didn't they send the cars across from Japan over Trans-Siberian railway? I was told that too many cars disappeared on the way. In fact, sometimes a whole train disappeared.
Now Russia has built a suitable harbour of its own closer to St. Petersburg so that the flow of new cars doesn't need to come to the ringroads of Helsinki (and, I expect, the economic situation means fewer cars are sold there).
