Have just read another article which makes it clear that there is much more involved than the autoexpress article reported. The regulation also requires that the following data be recorded: speed, braking, use of seat-belts, force of impact, indicators, engine/transmission data. This data , in case of an accident, only to be available to " people investigating the accident" ( no further explanation ), judicial authorities and research institutes.

Beyond this however for "new models" now ( and all by 2024)
Interface for fitting an ethylometer
Systems for checking alertness and driver reactivity
Systems to check for driver being distracted
Signals for emergency braking
Detection-systems when reversing
An accurate system for tyre-pressure sensing
Since a law for the last point already exists, they must believe it is not sufficiently accurate.
Bus and trucks
Warning systems to eliminate the blind-spots around the front of the vehicle to protect pedestrians and cyclists
Presumably any failure of any of these systems will result in a red warning -light on the dash so 10 or 12 years down the road will begin a massive scrapping of vehicles* because owners will not judge it cost-effective to repair the systems (if garages are in fact capable of doing so )
* or export to Russia/Africa/Asia.
