I plotted this graph just over a year ago:

The data at that time went up to 2022. I downloaded it again today and it goes up to 2023. So what's changed? Here are the differences. The graph shows, for each year, how many more (or fewer) cars are licensed or SORN. In theory each year should sum to zero as cars move between the two categories.

Interpretation:
Lots of cars between 1979 and 1982 seem to be back on the road, where they belong. This is excellent news.
There are actually 51 new cars between 1980-1982 that have appeared from nowhere. These were presumably cars that were never officially SORNed, just forgotten about.
This has also happened a bit in some of the earlier years. 14 new 1966 cars out of nowhere for example. Since many cars that age will have been completely rebuilt (at least once) I'm a bit suspicious that some people may be convincing the DVLA to re-register newer cars as older ones since they are more valuable.
Moving into the late 80s and early 90s the situation is less encouraging. Cars are coming off the road. We must try harder! Note that in UK cars older than 40y (i.e. 1984) have Historic status which means free road tax and some other benefits. Some of these SORNed newer cars will be being kept in good condition, just licensed intermittently to save money.
Here is the 2023 graph of absolute numbers:
