We no longer use satellite TV. We have the hardware to support data streaming from Verizon, AT&T or T-Mobile... whatever is the strongest. The only issue we have experienced was at a NASCAR race where the systems were overloaded due to the large number of fans at the race. Normal over the air TV broadcast is usually available during times like that. Streaming is "the next big thing" (already here) and Elon's StarLink system will soon be available for mobile applications too.

We don't normally watch TV while driving but it is certainly available when streaming. We do usually have Amazon music or SiriusXM music streaming.
