It's not the fact that they keep overtaking each other that really annoys
me. It's the fact that they take a long time to do it, sitting alongside the
lorry that they are overtaking for several minutes because of the very low
differential speed.
It cannot be easy driving a vehicle that has a very low
power/torque-to-weight ratio (and hence very poor acceleration) and which is
severely speed-limited. But that is what they are paid and trained to do -
how to drive safely *and with due consideration for other traffic*.
I've very occasionally found myself in the situation where my car runs out
of power when I'm trying to overtake, and I end up going no faster than the
vehicle I'm trying to overtake. But as soon as I realise what's happening,
I'll ease off the power or else brake so as to pull back behind the other
vehicle again, to have another go when I've got the gradient in my favour. I
don't sit there thinking "the longer I do this, the more likely I am to get
past" :-)
If I'm driving close to the speed limit and I come up behind a car that is
going fractionally slower, I don't immediately think "I must overtake",
especially if there is a lot of traffic in Lane 2 which is clearly going
much faster than I want to go. I may decide that 69 is as good as 70 mph, if
the alternative is to speed up to maybe 80 to match the speed of traffic in
Lane 2 until I've got past. But there must be something in the lorry
driver's mentality which says "I must go at 56.0 mph - 55.5 won't do".
To go back to the OP's question, I wonder if the fact that buses and coaches
are rigid vehicles whereas many lorries are articulated has any bearing on
the different speed limits? I presume articulated vehicles are more likely
to become unstable at high speed than rigid ones, if there is a crosswind
and the lorry starts to snake.
The other thing that gets me is the steep 1:4 hill (Sutton Bank) near me
which articulated HGVs are allowed to use but caravans are banned from
using. Almost every week (*) the hill is closed because yet another HGV has
got stuck on the hairpin bends (either because of the tightness of the bend
or else the steepness of the hill - I'm not sure which). And all HGVs have
to take the hill exceptionally slowly eg 10-20 mph when a car can do the
straight bits (though not the tight bends!) at maybe 40 mph.
The hill really isn't suitable for HGVs in the same way that it's not
suitable for caravans. It doesn't help that the road is a bit too narrow for
cars to be able to do a U turn if they find that the road ahead has been
blocked by yet another HGV. The excuse that the Highways Authority give for
not banning lorries is that it is an important route to the towns nearer the
coast and that (unlike caravans) there is no suitable alternative route.
Which is fair enough, as long as they make it clear that lorries (and their
drivers) must be capable of getting up the hill, with those that don't being
subject to a large "you'll never ever do this again" fine - such as
confiscation of the offending vehicle!
Perish the thought that hauliers might actually use vehicles that are suited
to the size of roads that they are using - eg smaller vehicles on the Sutton
Bank route.
(*) On the Google Streetview 2015 photo
https://goo.gl/maps/TdYa1SuQUM22
they record that there were "74 blockages by HGVs last year" and on the 2011
photo it was 132 which is an average of one every three days.
