That's because no one can afford to drive in Oslo any more. Every road is a toll road and there are no parking spaces any more.

That’s quite an exaggeration, though I understand how it can seem that way to some. Anyhow, it’s the middle of summer vacation, so lots if people are out of town. But more to the point, the meteor was visible over an area vastly bigger than Oslo. Even more to the point, dashcams aren’t that common in Norway, I think (though I have no data). In Russia, they are said to be very common as a defence from corrupt police and wrong claims of other drivers in case of accidents.
