All it would need is a wi-fi antenna internally, and then it could connect to an open wi-fi network anywhere. And it's going to be pretty much impossible to avoid ever driving your car within range of some open network.
It would have to find an open Wi-Fi network that isn't gated behind a captive portal, which is very rare. Rare enough that most telemetry would be too stale to be useful.
