I used to be on the engineering team that worked on the development of a similar camera. For what it's worth, at the time: there was no AI involved, we only used good old image processing algorithms. And the camera (all cameras, lidars, or radars on the car BTW) does not record anything. It treats images as they come. There's almost no storage space on the car for all the image data generated.
All this might have changed since then (especially the AI part) but I'm still relatively confident that car systems don't have the storage for all this data.
Additionally, since this is a European brand, I think it would be quite difficult to legally retain personal information like that. It was already difficult during the development phase.
I'm not saying they wouldn't be above ominous shenanigans, but it would be difficult.
