One thing I’m concerned about is recording equipment leaving identifiable information without us knowing about it.

I hate this.
I’m still driving a '99 vehicle and the most advanced thing about it are the power windows. I dread upgrading to a vehicle that can break in so many new ways. I hate that everything has touch screens and the software on many is awful and if it breaks, surprise, you have no music in your car now.
Those still have an ECU that stores most of the same data. It knows you speed, it knows how hard you brake, etc. anything with an OBD will store data. And that’s carssince the 70s
Depends on the car. Most older cars are concerned with basic OBD stuff, faults, and engine management. I have a 2012 and it doesn’t record anything interesting at all. Just engine data. You are right though, a few do save data, I just don’t know which ones, what year they start, and the depth of data recorded. The ‘70’s still had most cars running a regular analog mechanical system or maybe an electronic ignition controlled by an ECU. The ECUs most similar to today’s started becoming more common in the ‘80s.
You’ll be surprised, they take snapshots at certain points. In a collision all vehicles will store last 5 or so seconds of data, speed, see if brakes are engaged, stuff like that, it’s all used in collision investigations. There’s not a single car I think that’s doesn’t do this. As I said, it’s in some form, but your vehicle does know if you’ve sped if it has an obd on it.
What do you think basic OBD stuff is? It’s all that information and that’s used to see if anything’s wrong with the vehicle.
I’m pretty familiar. I think you’re more referring to modern CAN bus systems that record everything under the sun. Basic ECUs from back in the 80s just didn’t do as much. Even my ‘12 only has OBD2 and the data collection is limited. I have so e fairly advanced diagnostic equipment to read all this stuff. The only thing I can’t do is program it, but I’ll be doing that soon enough.
No, even ODB from the 70s records you max reached speed, if you’ve hit the governer/rev limiter and how many times.
It’s nothing modern, modern just does it more frequent, more situations, more information, more data points, and mandatory black boxes.
And many vehicles from 2000 onwards have dedicated EDR boxes, what make and model and trim is your 2012?
So sounds like you don’t quite know what’s going on under your hood there ;)
