A modern high-end BMW can have over a hundred separate ECUs (microcontrollers). All communicating over multiple CAN and FlexRay networks. The complexity is mind boggling, just so you can have subscription based seat heating and other nonsense.

No technician on Earth will be able to debug this black box spaghetti except the manufacturer. If you try to access/reprogram one of these chips (as you should be able as you OWN the damn thing), the microcontroller has OTP (one time programmable) memory that ensures the device can physically brick itself should you try.
