They definitely do. The vast majority of cars (Tesla being a notable exception) run their critical systems on CANbus with AUTOSAR and QNX or VxWorks. That’s why their entertainment system can still crash while the car drives on just fine. That doesn’t mean one can’t obscure the other; on VW group cars, for example, the reversing camera is run by QNX on CANbus but shown on the entertainment screen as an overlay. Occasionally you’ll see QNX starting to show the camera before the entertainment system has had a chance to draw the frame around it.
