Yeah... go out and start it, for whatever value of "start" you need. I frequently walk out to our Volt and start it to let it warm up the cabin on shore power, though I can also do it through a window with the key fob. Or I'll even go start a motorcycle to let it run for five minutes before I head out in the winter. I'm really not sure what I'm going to do with cars in the future. The Volt is the last wave of not-always-connected-software-OTA-big-data-analysis cars, and even it had Onstar, it just tries to talk to towers that no longer exist. But there's a difference between that sort of system and what newer cars have. I suppose you can always disable the cell modem and let them have occasional wifi access to update, but... ugh.
