If my ICE runs out of gas, I can use a gas can to add emergency fuel. What happens if the public charger I'm counting on is out of service or I fail to notice my charge is low and I'm too far from anyone's exterior power outlet when I shut down? Can I hack-charge my Model S? Specifically, can I clip on a charger/starter or a standard 12V somewhere and add emergency power to the battery and limp home? I'm asking in part b/c I have a poor man's solar-powered cabin 100 miles away (and 5000ft up). I'd love to connect the S into a solar panel and inverter for a little extra range so I don't need to stop on the way there or back for an hour. Please don't suggest I get the 85. I've already somehow talked myself into the 60. And while I'm in survivalist mode, what happens if my Model S blows a tire? I have a spare in the trunk of my ICE. Aside from space, is there any reason not to carry a spare in one's S? I don't play golf or do the food shopping. I'm not sure what I need all that space for besides a spare. Thanks for your comments.
