Bad omen?

Any points for a new driver could be expensive. Six points, meaning back to square 1, would be disastrous. It's not worth risking.

Indeed - much better to commit these little indiscretions abroad, where points are not (yet!) applied to your UK license.

I avoid the M4 wherever possible. In the past though I've found that it has the highest average cruising pace I've seen for cars, even during busy periods. Driving along at 80ish I wasn't overtaking much apart from HGVs.

Not so sure about that. Even if they can't touch your license for points, the fines can be large, and they will confiscate your car if you can't pay.

Or indeed suspend your licence on the spot and then confiscate the car if there's no one available to drive it thereafter. A friend of mine had this issue whilst driving a McLaren 650S this year.

Would it be too off-topic to mention speed differentials? :D

If overtaking to make progress, because of traffic conditions or the speed limit, would result in small differential (for argument as that seems often on-topic ;) ) maybe 2/3mph only should one simply forgo it and stay back?

A friend once suggested that there were two sorts of overtake - one where you will be able to make significant progress and those for ego's sake, where you overtake just because you can.

I'd suggest in your description above that the ego would be to the fore...

I'd agree with that.... Somewhere in my head I have (probably falsely) that on AD test and making progress one should utilise even small differentials. I can't see the point really. It would be different if I had a blue light on top....

It seems to me that patience when driving is a virtue.

Sorry to be pedantic, but I rather think there had been a car swap, and he was driving the F12 of another mutual friend. It cost him 750 euros and the suspension of his right to drive in France for a while, for a brief burst of safe speed away from a toll booth on an autoroute. HIs wife drove the F12 for the next few hours. I take an interest in these things having myself had to part with 750 euros to at a gendarmerie a few years ago - in my case, as in this, for just more than 50 kph over a French national speed limit. In this country we would probably have experienced bans, with in consequence large increases in insurance costs subsequently.

Not sure what you mean here. On an AD test (or according to the law at any time) you should not plan an overtake unless you expect to be able to complete it within the speed limit. Since you would not wish to spend a long time alongside another vehicle, this surely means that you should not plan an overtake unless there is an adequate speed differential. What is adequate? That depends!
