We got tagged by a robo-cop a couple of weeks ago, and they finally got around to sending the ticket. I was driving the equivalent of 59 mph in a 50 mph zone (95 kph in an 80 kph zone). In the U.S., I don't think you'd get pulled over for that. In Norway, it's a $500 offense. They say I'm lucky, if I had been driving much faster it could be thousands of dollars and loss of license. I guess the moral is, when you're living in one of the richest countries in the world, beware of the fines! The natives can afford much more than you can!
Incidentally, the name of the tunnel is Helltunnelen, or "Hell Tunnel." No kidding! Apparently, the radar camera brings in millions of dollars each year in fines. Helltunnelen is a few meters shy of 4 km (2.5 miles). The longest tunnel in Norway is the longest tunnel in the world... a whopping 24 km... that's 15 miles long! Here's some data on the tunnels in Norway, a public education service of the Naylors in Norway blog.
