No - that doesn't work. I did not say I was overtaken. The post was about one lorry overtaking (although materially that is not what they achieve!) another whilst traveling at almost the same speed. On many A-roads this causes congestion spot after congestion spot. So they reduce the average speed on a 2-lane carriageway to the speed of the slower lorry in the inside lane.
I actually buy very little in order to do my bit for the planet, but this is not relevant when considering driving skills.
