Although electric can't be 100% analog, I miss the old days when a car has no software updates, no telemetry, no privacy issues, no mandatory subscription for features.

* 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.).
I wonder if regulations would allow for a sort of periscope system.
(Not that it would be practical.)
Video for a backup camera is mandatory on new cars in the US and Europe, so it makes sense to use the same bus.
And TPMS. And key-fob remote lock/unlock. And BTLE for BYO music / calls.

This is the one big thing that has me leaning towards "used, 2015 or older" for my next car. With an EV, you really do want a way to specify how much power / when should be used for charging though; some "discounted" electric utility plans require being able to shed / schedule big loads on demand, too.
If this vehicle doesn't have any screen, you need to use a phone or similar to configure all this. Yes, schedule data can be done over BTLE, but something big like an OTA update can not be (at least, practically).
There's also a lot of value (for some people) in being able to change/monitor charge capacity from distances further away than what BTLE would support.
If the modem could be toggled and there was a USB port for software updates, I'd be _thrilled_.

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.
[1]: They also have control pins to tell the car the maximum amperage they're allowed to draw, but that's not relevant to the feature of "disable the charger when I don't want it charging"
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 car makes all the decisions about how much power to draw and when to do it. Excluding the DC super/fast chargers, the hardware on the wall is pretty "dumb".
It's been pointed out elsewhere, but remote notifications are useful so you know it's time to get out of the public charger and let somebody else in (or to go back out and check on why it's suddenly stopped charging)
Obviously it is too limiting for modern cars so it will get mostly dropped. It clearly is a great protocol though.
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.
