This 15-mile tunnel is just one in a seemingly never-ending series of long tunnels along the road out of Bergen.
I've driven it several times, but never as quickly as this (the 20-minute drive is here speeded up by a factor of eight).
If you're so desperate that you're even prepared to watch a film of driving through a tunnel, you'll notice three brightly-lit caves.
In real life they're even more dramatic because as you approach them at a normal speed you become gradually aware of the approach of dawn and then emerge into a brightly and colourfully-lit cavern.
The reason is that the tunnel designers were worried that drivers would secumb to the monotony of all these miles of dark tunnel with hypnotic street lights, and fall asleep.
So the caverns were put in on the advice of psychiatrists in order to introduce changes of perspective and lighting - just in order to wake up semi-comatose drivers.
