Auto pilot still works when you restart the infotainment and display system (holding two buttons on the steering wheel down), so the systems aren’t powered by the same OS.
It is only half of the story. I was almost sure, that ECU and Infotaiment runs on different CPUs under different OSes. Question is, what do they share? Same bus? Some memory area? Or only something like I2C?
I could imagine situation, when hacked infotaiment system overloads power supply, and if power supply is shared, it takes down ECU too, for example.

That's not how auto engineering works. Read up on Controller Area Network (CAN)Bus. Tesla MCUs (Touchscreen) are on a completely separate sub-system from the power-train/braking systems.
> I hope, Tesla's engineers better than that.
Sure. Most of Tesla engineers came from other auto manufacturers. Lot's of them were form the UK during the development of the Model S.
