This tech has been in US market cars since 2000 but there has been no standard on how to access it or what is recorded and for what period of time. All the Euros are doing is making auto manufactures standardize on all of those, just like the US OBD-II standard made manufacturers standardize on basic diagnostics.
It’s just a ruse of sorts. Anyone that has a cellphone turned on in the car is carrying a portable “black box”. It has the added feature of pedestrian monitoring too!
