Have you ever driven? If 80% of the drives in front pulled over, the 20% who didn't would pull into the open space and floor it. I've seen lots of people cut off or tailgate emergency services. I've pulled over, completely off the road, and stopped before an intersection, so I left it clear for the approaching fire truck. The person behind me pulled in behind me, but failed to stop completely, and hit me. He saw the truck, pulled over, and slowed, but missed the car in front, and managed to hit me.
Perhaps you drive on different roads, where drivers are polite and attentive. But that's not the roads I've driven. And yes, I've driven in Europe, though not Sweden.
