What do you mean by "analog?" It's not possible to make an "analog" vehicle of any kind due to regulation:

* It would be impossible to pass modern car emissions standards without electronic engine control.

* Backup cameras are mandatory, so you need an electronic pixel display somewhere.

* Lane keeping is required in Europe as of 2022, so that's a suite of sensors and computer-steering as a requirement.

* AEB will be required as of 2029 in the US, so that's a full electronic braking system (some form of pressure accumulator/source, solenoids/valves) and forward looking sensors (radar, lidar, visual, etc.).

The vast vast majority of backup cameras ARE analog, including all the little one inch cubes you see poorly mounted on the back of sedans, and including the ones VW/Audi uses.

You could in fact plug their signal into a tube TV from the 50s. You might lose some overlay features.

If you want any one of:

Smooth running. Reliable start. Smooth Throttle application and resistance to all the problems we had with carbs. Airbags. Automatic management of cold weather performance.

Then you REQUIRE electronic actuators, sensors, and microcontrollers.

How many people know what a "Choke" is anymore?

The camera<->head unit signal modulation is analog but unless the display is a CRT, both ends of the system are digital.

This is basically why I was asking “what do you mean, analog” - I suspect the OP really wanted either no touchscreen or no telematics, which are totally unrelated to whether the systems are analog or digital.

There was a whole generation of very cool analog computer fuel injection (K-jetronic for example) that avoided most carb problems for end users without going full computer - but, there wasn’t a chance these kinds of system could continue to pass modern emissions standards.

I wonder if regulations would allow for a sort of periscope system.

(Not that it would be practical.)

The specific regulation is here:

Nor practical but an analog system could probably meet the standard.

Rearview image means a visual image, detected by means of a single source, of the area directly behind a vehicle that is provided in a single location to the vehicle operator and by means of indirect vision.

Rear visibility system means the set of devices or components which together perform the function of producing the rearview image as required under this standard.

5.5 just says it needs to meet certain testing standards, start displaying within 2 seconds of backing up, and stop displaying when driving forward.

FMVSS does in the US, but it'd have to be very steampunk to meet all the requirements.

A lot of delivery vehicles used to have convex mirror behind to give an idea where the bumper is.
