There is literally no reason for automakers to do this, and yes I know now the FUD comes in "well they will cuz reasons! cuz gubbmint!"
But just like the rear view camera... you're imagining that they'll spend significant time and money to do something with no use other than incriminating themselves...
So sure maybe your rear view camera can be rigged to stream to their servers 24/7, some already record and upload incidents anyways right?
But it's a massive jump from the happy path.
This is 100000x easier to do on the car without looping in a remote server and opens them up to 100000000000x more liability if the interface is hacked.
They wouldn't do it.
That might be the best example of a straw-man that I've ever seen.

I think that was the point.
Replace "rear view cameras" with "onboard tools to detect and deter/prevent impaired driving" and you have the same straw man.
Proof? It already happened: driver licenses already went through every one of those steps, getting hijacked way beyond the original purpose of denoting that you had the training to drive a car, into government-imposed threats against all sorts of "bad" behavior.
I don't trust any expansion of government power in good faith.
