Sometimes both. My car can connect to my home's WiFi for its software updates. I doubt that antenna is inside the cabin of the car. It also can act as a hotspot if I bothered paying for its data plan. I'd rather if I could just load an eSIM for my existing service to have it be a hotspot for me. Since its antennas are on the outside it should get way better GPS and cellular connectivity than my phone in my pocket deep in a metal box.
