In the short term plowed roads can be more dangerous as it may expose the

Well, if you're an idiot, then yes. Seems to me that if you have a
4WD, it's really not an issue. I never had any problems with my old
CJ7 either on ice, thinly covered ice, plowed streets??, or fairly
deep stuff.

Snow tires don't work on ice. They need snow for the tread to grab. The snow
can have some adhesion to ice. So, in some cases unplowed roads offer more
traction.

Well, I took a long slide on ice once with my Jeep... part of the road
flooded then froze over.. maybe 100 feet or so.. just put it in
reverse and gently applied some gas. Came to stop without hitting the
pole at the end of the road.
