Regarding lane discipline :
I baulk at mentioning his name but, iirc, BAS used to point out that a few miles per hour of speeding made bugger all difference to most journeys, so speeding was pointless as well as selfish, dangerous, and illegal.
Which makes lorry overtakes - elephant races - even more futile, for the half - an-mph gain they make.
They should ban elephant races, full stop.
