Love the new route generator, which shows the gaps in the international roads network in sometimes quite dramatic fashion. Have a look at the distance between the Utterland town of Luikenberg and the Isztiarnorszag town of Szarvasko. Approximately 150 km as the crow flies, but an eye-watering 2080 km by road.

Do I advocate linking our countries' road networks? Depends how everybody feels about that.
