What we really need is for all of the logs from a company like Uber or Google to get streamed to some third party.

All of the logs are encrypted (with different keys), and only when an issue occurs, the company who owns the data gives the key for that particular car at that particular hour for decryption. Basically a data-escrow.

This way we know the logs are not being tampered with, and we keep the data hidden from the third party.

These are test vehicles. If you don't let the engineers have access to the results of their testing except in the event of an accident, then we will never have autonomous cars.

Of course, maybe thats what you're arguing for. But either way, I think it's a bad idea.

No reason you couldn't do both.

Test vehicles collect all the data. I think it was Cruise that mentioned they collect about 4 terabytes per day per vehicle. It likely isn't much different for Uber.

I believe most modern cars already have this.

Yes; in fact, cars have had this technology since before there was flash memory or GPS or (good) accelerometers. https://en.wikipedia.org/wiki/Event_data_recorder s were originally designed to record the instantaneous mechanical state of the car (e.g. whether seatbelts were buckled, to what degree the accelerator was depressed, etc.) during a crash, for insurance purposes.
