There seems to be a difference in trucker culture between the US and UK - truckers in the UK don't seem to practise this technique.
While there are some courteous and sensible UK truckers, most of them seem to be driving right up against their speed limiters, and will tailgate then overtake anyone in front who dares travel 1mph slower than them - even if this involves attempting to overtake while going uphill, causing a wall of congestion on an otherwise free-flowing motorway.
