Exactly, I've been changing my consumer habits towards products that either don't need maintenance at all (GoRuck) or are optimized for ease of maintenance (Fairphone). Sadly haven't found an EV (or a modern IC engine car) that matches these criteria. All the systems and components are sitting on a CAN bus anyway, in the base configuration you can just control the CAN master with analog switches like in the old days.. You can make a paid mobile app for the same controls but digital (and allow more fine-tuning). This eliminates the display from the car though, so I guess a parking camera is a no-go. All you need hardware-wise on the car at that point would be a CAN Master device with bluetooth, which is a stupid ESP32.
