It is exactly how it works. There ~40-115 different computers in a modern car that often have completely walled-off modules running on them. Most 'models' you will find in a car's software aren't even generated through machine learning, but tried and true engineering/statistics. No one in their right mind is proposing to replace those with one big AI monolith. That's marketing BS from the likes of NVidia, who would stand to gain from it. AI is being used in certain subfunctions like visual object detection. In the future, AI will be used to make higher level decisions like trajectory (lane choice, overtaking etc.) and route planning. But it will only hand those higher level plans down to the mostly 'dumb' computer systems of the car to be carried out just as with a manually driven car.
