If you'd ever sat behind 2 "elephant racing" lorries for mile after mile
after mile

I have seen the entire M4/A34-M3/A34 slowed for 27 miles because of a
series of lorries playing roadblock.

I also notice that the stretch the other way (towards the M40) *does*
have restrictions in place to prevent this behaviour. The landscape
geography is no different to the M4-M3 stretch. However David Cameron
does live there ????

Yes I've been a victim of them on the A34, from M4 J13 (Newbury) to
Didcot many times. It's better now they've brought in the HGV-overtaking
ban on Gore Hill (the steep hill just south of Didcot), but it's still a
problem - mainly because so many HGVs use that route from Southampton to
Birmingham.

M1 from M18 to Ferrybridge (start of 3-lane motorway rather than 2-lane
dual-carriageway) is bad too at times.

That's such a short section (~ 1 mile?) that it doesn't really make any
difference.

The main problem comes on level sections, where a lorry's speed is
determined by its governor, more or less regardless of the state of
loading. So when one lorry overtakes another, the closing speed is
determined by slight differences in their governor settings - and the
manoeuvre can literally go on for miles.
