I'm sure this is gonna raise the hackles for quite a few here but I see a lot of "I'm helpless come save me" type thinking going on here.
TeacherRO is the only one so far who touched on the right direction... snow shovel, jumper cables, flashy light, etc
Doesn't anyone prep for self-rescue anymore?
How about tire chains, a satellite phone, a tow rope, tools, shovel, tree saw, shoe spikes. Think self-rescue - Don't just sit on the side of the road and pray the government will save you before your little candle burns out and you freeze to death.
To some extent, most of us probably do. But replacing a battery, or replacing an alternator, isn't exactly the type of thing most people pack for. Sure, jumper cables, but sometimes you really do need to tow it somewhere, either for parts, or a mechanic. Notice that Dangy lives in D.C., she's not off-roading in the boonies somewhere.
Now, if she had a long rural commute, or was out in the Mojave, you'd have a point. She'd also probably be traveling with another friend in another vehicle (at least, if she was off-roading). How often do you drive with a wingman in your daily commute?
