To answer your Q Doc, Inexperience, I was not saint but there again the speed limit then was 60, I shudder when I see the HGVs travelling so close & what & has happened, the cabs of HGVs are no thicker than a car just because they are high they can still crumple & especially when the run up someones Else's @rse & like many on here we have seen it, the only advantage you have in a HGV you can see a long way ahead ( If you are an experienced driver that is) I will not stick up for the HGVs there are some Knob heads that think they can drive the things, I stated a few weeks back, you can learn to drive these things in a week pulling an EMPTY TRAILOR then the government in their wisdom allows the INEXPERIENCED KID to drive a BIG lorry carrying 44 tonnes, you tell me that's safe & I'll show my @rse in Marks & Sparks. Regards HGVs swinging into the middle lane as you put it, there is an @rsol the has been stuck close distance behind the HGV in the middle NOT MAKING PROGRESS getting the driver pzzzzzzzzed off, It only takes a car seconds to get out of the way but it takes a HGV a long time to pick up the revs because of the weight he / she is pulling, I hope this will answer some people inexperienced USE of the Motorway network.
