I was on vacation in Norway, driving from Oslo to Bergen, when I happened to take the Vallavik Tunnel and came across a roundabout in a tunnel for the first time in my life. The length of some of the Norwegian tunnels is mind-boggling enough (the Lærdal Tunnel is 24km/15 miles long!), but coming across a dramatically-lit roundabout in a tunnel made me feel like I was in Mario Kart or something, not the real world.
