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.).
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.
