I live in north-central Idaho. 10 minutes from 2 state-universities, but in an otherwise relatively rural part of the county with a 1/4 mile long, somewhat steep driveway.
Every year, I'm amazed at how quickly our personal "veneer of civilization" collapses in the snow.
The prior owners of our home would just keep their kids home from school, and work from home an average of "about a week every winter."
We're a little more aggressive with snow removal, but there are still mornings every winter where I'm getting up at 5 to spend a couple hours plowing and blowing out drifts on our driveway (after typically doing the same thing the night before) just in order for my wife to make it down to our county road which might still have a foot or so of snow covering it.
Similarly, in windy snow-covered conditions, there are a couple spots between us and town where the snow regularly drifts back over the road in a matter of hours, causing a "well, I know the road goes about here, I think I can make it through these drifts if I floor it so here it goes" situation.
Even when the roads are well plowed and clear, there are plenty of situations where it's difficult for me, a human, to distinguish between the plowed-but-still-white-road and the white snow all around it in some lighting conditions.
And let's take snow out of it. Our fastest route into town involves gravel roads. And our paved route is chip-sealed every couple years, and typically doesn't get a divider-line drawn back on it for 6-months or so after.
Which is all to say, I think it's going to be quite a while before I have a car that can autonomously drive me into town in the summer, and global warming aside, I'll probably never have one that can get me there reliably in the winter.
