Backup cameras have been an optional extra for a long time sure, but I don't think I'm aware of any car that actually comes standard with one. Well, maybe a Mercedes-Benz S-Class. I do have a backup camera in my 10-year-old Benz, but I imagine that the original owner paid a four-digit amount of euros for it back in the day.

'Rear Visibility' is required in new cars in US by FMVSS 111. Test procedure mandates field of view to rear of vehicles during backing, that are practical to satisfy with cameras. mirrors would require like a periscope to satisfy.

Yeah, but the US isn't the EU.
