I remember that. Doesn't stop me from doing it thoughI remember watching a BBC documentary quite a few years ago where 4 cars were setup with large A, B, C & D on their roofs.
They went on the motorway for 1 hour and car A could only stay in the 1st lane, B in lane 2, C in the outside lane and D could go anywhere.
At the end of the hour D won by about 30 seconds and the difference between D and A was about 2 minutes over the hour.
I don't know why I bother being a C or mostly D and breaking the law some of the time.

I know that my aggressive driving just wastes money in petrol and wear and tear (gear changes, bla bla). I just can't sit in one lane behind a lorry doing 50mph everywhere. I literally fall asleep.
FWIW, when I was in Norway, I remember overtaking a car (doing the speed limit) about 30 miles before the ferry on rural roads in the fjords.
The limit was 80km/h, and I was probably averaging 90-100.
It took me a little over half an hour, and the dude I overtook turned up to the ferry about 6 minutes after me. All that extra fuel spent driving faster and overtaking for 6 minutes. And we both caught the same boat...
