> I don't see a meaningful distinction between a screen on a DIN unit and an integrated screen.

Someone questioned why a car needs two 12" touch screens.

To which you replied

> Backup cameras are an enormous safety improvement.

My entire point is, that there's zero relationship between having a backup camera, and needing a 12" touchscreen, or a touch screen of any kind.

If your backup camera needs a touch screen, you've already failed. The entire point is that it activates automatically and deactivates automatically.

They've been available for literally decades - Toyota had a production model with a reversing camera in the fucking 80s.

Nothing else you've said since is related to your claim "Backup cameras are an enormous safety improvement" and that claim is completely unrelated to OP's question about why a car needs not one but two 12" touch screens.
