In modern cars you’d need to actually rip the dashboard apart and cut the power to the built-in eSIM cellular antenna. Cars these days use cell towers to phone home, not just Wifi. And oftentimes, disconnecting that cellular connection will also disable major features of the car (like the radio and Bluetooth, which you claim will work just fine) because it’s all integrated on the same circuit board.
In some cases your car will even fucking throw error codes that will cause you to fail a state inspection. Meaning you’re forced to reconnect it before you can pass inspection and update your car registration. And nobody wants to take the time or effort to rip their dashboard apart every year for inspection. Auto manufacturers know this, and it’s exactly why they do it as a deterrent.








Steam also supports local file transfers for game downloads. Like if your PC has a game downloaded and you start to download it on your Deck, the Deck will ask if you want to download it directly from your PC. It means your download speed is primarily limited by your LAN and PC hardware, (which is probably at least gigabit these days), instead of whatever arbitrary speed cap your ISP has implemented.
But technically speaking, carrying an SD card across the house would likely have higher data speeds. The latency sucks, but the bandwidth is only limited by the size of the card and how quickly you’re able to walk across the house. Hell, if you have a stack of large hard drives and it only takes you a few seconds to walk across a small living area, your total measured bandwidth could be measured in tens of terabytes per second. There’s an old joke that a carrier pigeon flying across town with a stack of SD cards would have higher bandwidth than any modern network.
