Since there really are no traffic jams in Finland, my experience is that the phenomenon is worse here. In more populated countries drivers must deal with sometimes occurring reduced speeds like adults, but in Finland there usually is enough space for a single driver to keep their speed at 115% of the limit, due to other drivers facilitating the selfishness. If someone does not facilitate, the speeder will get aggressive and has to find someone to blame for their (actually, his and his car’s, which has more civil rights than a leftist) misfortune.

In Germany all drivers have to accept that there isn’t enough road capacity so everyone could drive as fast as they want and the Staus cannot be blamed on the car in front of you. It’s also common to drive under the limit, in Finland 115% of the limit is the socially acceptable minimum.
