Norway and transportation
For a country with a modest 4.5 million, Norway is surprisingly big, beating United Kingdom (6o million) with almost 80,000 square kilometres, or One Czech Republic. Given Norwegians' general mistrust of neighbours, they have seated themselves as far away from each other as climate allows. The four largest cities prove this:
Oslo - Bergen: 467 km (7 hours by car)
Oslo - Trondheim: 500 km (more than 7 hours by car)
Oslo - Stavanger: 452 km (roughly 7 hours by car)
Bergen - Trondheim: 633 km (9 1/2 hours by car and one ferry)
Bergen - Stavanger: 189 km (roughly four hours by car and three ferries - if they are on time)

There are four trusted ways to get between the cities:

By car: The main difference between Norwegians and other drivers is that the traffic laws and rules, such as giving way for the car to your right, are actually respected. In fact, compared to most of the world, driving in Norway is a breeze as far as other drivers are concerned. Just remember, don't use your horn. It is not becomming in Norway.

That's the bit about other drivers. As far as gas prices are concerned, they are very high. While they are not highest in Europe, Norwegian prices are heavily taxed, and it is believed that 80% of the money are taxes. This is among the top political causes in Norway, which gives you some idea about the problems there. Also, there are quite a few toll booths and if you are planning on eating while on one of these trips, you should bring a lot of cash.

By train or bus: If you decide to take the train, bring a book or something else to while away your time, and be early. Trains either leave two minutes before or half an hour after schedule. Also, buy food before entering the train, as even Norwegians think that train food is heavily overpriced. Speaking of which, you will be paying through your nose to use the train.

Taking a bus is roughly the same, only they rarely have any food serving on board.

By airplane: Don't buy any food on board, and you are good to go. There are inexpensive flights, but remember to add roughly £ 200 ($326) to the price in hidden expenses if you are flying with Ryanair. If you travel with Norwegian, you need only add £50. On the plane, Norwegians might appear drunk and disorderly, but this is really true only for about 10% of the travellers. The others are merely disorderly.

Regardless where you sit, Norwegians will, if at all possible, avoid sitting next to you. It's not you, it's the Norwegian way. Perhaps Norwegians need the free air, perhaps they are over-sensitive, perhaps they are loners. Social at public transport they certainly are not.
