alt Hacker News- The mandate is for rear visibility. Car manufacturers choose to implement it with the back-up camera. Beyond that, it's obviously safer to be able to see everything behind the vehicle.
- My vehicle has a backup camera with a screen, but has physical buttons for all controls (A/C, audio system). There's no reason cars can't have both.

When it already has a screen it's much cheaper to get rid of the buttons then. The screen as a requirement is priced in whereas the buttons are not and thus cut.

Specifically, 10 feet by 20 feet directly behind the vehicle. I'm actually curious how this could be achieved with only mirrors. That's a pretty big swath for anything with a viewpoint where the driver is sitting.

Early implementations just used a screen in the rearview mirror. No need for any kind of infotainment screen.
