Had a grand total of 9 points (3 SP30/60s for speeding only) in the space of 20 years, and I've not changed the way I drive as on two of those occasions I'd do exactly the same now.
1st one (about 12 years ago) was on a 50mph DC when a dozy git in a people carrier decided to pull out in front of me without indicating and sit at 30mph alongside the equally dozy git in a van doing the same speed. This guy must have sat there for about 2 miles before I'd had enough and flashed/beeped to get his attention. He dabbed his brakes, so did I, and he pulled back in behind the van

so I dropped the M5 into 2nd and blasted past just in time to see a copper standing in the slip road pointing a camera at me - so I waved to him and got a ticket a few days later.
2nd one (about 6 years ago) was when I was returning home from London one Friday afternoon. Driving along my usual NSL DC, dropped to about 60mph before the road tightens at my slip road. Next thing I know a copper jumps out from around the bend and gestures me to pull in. I pull in and when he asks if I know why he stopped me I tell him I genuinely thought they were just doing random stops. He tells me I was speeding by dome margin, and I effectively tell him to stop pissing me about as I know I was doing almost exactly 60mph. He agrees and I'm confused until he tells me the limit has been reduced to 40mph as they're preparing to put a set of traffic lights & junction in. It had been 70mph on Monday, the rest of the road was now a 60, and this bit was now a 40. He didn't seem receptive to my suggestion that I should get away with just a warning due to the lack of adequate signage warning of these changes. Didn't bother appealing on that technicality
3rd one (about 6 months ago) was on a Welsh hoon. Just joined the A5 after doing the Evo, came up behind a 6-series doing 50mph. Road widened enough for me to see ahead clearly so I dropped to 3rd, pulled out and started to pass. Bastard in the 6-series accelerated, so I did the same, but harder & faster. Got past, pulled back in when well clear, lifted off, and got the main beam treatment. About a minute later I see blues & twos in my mirrors and a marked up 5 series indicates for me to pull over. Copper gets out, says he saw the overtake - which in his words was "Fine, but just a little bit too quick". Told me that I was way over the 60mph limit, told me I'd exceeded 90mph at one point in the overtake, but would escape a court appearance and record the speed at the ticketing threshold of 86mph as I'd overtaken and dropped straight back down to a more reasonable speed. He even told me (although I doubt it would hold up in court) that they wouldn't have even looked at me at below 75mph.
