For #1, don't folks in cold climates normally use an electric engine heater to get the gas car started? When I was planning a trip to Tahoe, during inclement weather, I figured my new RAV4 Prime (a hybrid) would be perfect. I'd drive the whole way on gas and keep the battery fully charged; if I got stuck on Donner Pass, I think the battery can keep the main compartment at a reasonable temperature all night without running the ICE. Fortunately that never came up but it was an interesting thought at a time when folks were getting stuck on Donner for 10+ hours.
