Don't know about other countries but in Holland its goddamn awfull.
130km/h road, trucks can drive 90 max. Somehow they always feel the need to pass eachother going 91 km/h taking 5 minutes to pass one another holding up every normal car in line up to the point of causing traffic jams and accidents because people have to emergency brake.
I feel like they doing it on purpose to piss off the regular highway user.
Any truck driver can shed some light on this?
