I know several people who own Subarus with the TSS system, the cameras do not record, they just monitor for traffic and road lines in front of you
Does the Toyota one? Have we actually seen proof in the form of a video recorded from it that suggests that that video is being harvested and kept?
Some cars do have cameras in them from the factory. I think someone might have mentioned the corvette at some point, which with a certain package does. But that option is specifically there to let people record their lap times if they want and it has a way to download that stuff.
I'm unaware at the moment of any way that the camera system on the 4runner does the same, which is why I'm not too concerned. My understanding it's essentially live video without a storage device. The video is interpreted in real-time by the computer and then purged.
The car absolutely does log driving habits, as evidenced by the "drivers score" and the breadcrumbs stuff available in the app. But that still isn't some clandestine attempt to record millions of hours of video from millions of cars on the road for some sort of data collection.
As an aside, if the camera system did record, it would be pretty nice to have it in place of a standalone aftermarket dash cam. Assuming of course that you and you alone had access to the saved video.
Regardless, I'm betting that the camera on the 4runner doesn't record anything at all. It's a live feed, that's it
