They’re starting to put LTE modems in all cars

Because a lot of the market also wants to be able to monitor and control certain aspects of their car remotely, and this is only possible with remote internet connection. LTE is the cheapest and best way to get this. I know it’s unfortunately also used for data collection, but at least it provides some useful functionality for the user as well.

But TVs are pretty much always located near a network source, either wireless or wired. There’s not really a need to implement LTE, that they have to pay for, when they can just use the customers network. Since 99% will connect to the internet, the last 1% are not an interesting market share for them compared to what they would cost.

I kind of doubt LoRa is used for this application because the bitrate is super low. Transferring any meaningful amount of telemetry is not feasible.
