That’s definitely a possibility, depending on the year and make. Now you’ve given me something to think about.

I bought a used Chevy Bolt, then disconnected the antenna to put a dummy load on the OnStar transmitter. Never told it my Wi-Fi password. It can’t connect to the Internet unless I park it next to a cell tower, unless I pay for OnStar, which I refuse to do. I only use CarPlay so it can’t even hope to use my phone’s Bluetooth tethering (not that it seems capable).

Fortunately, Chevy’s only OTA infotainment update was to remove the video player, so I’m not missing much. Unplug the power cord and drive.
