it can get worst
A few years back, the night before the snow storm, I thought my sis in law was over reacted when she decided to stay in the hotel next to the hospital, where she worked, as she was afraid of not being able to drive to work on the next day according to the weather broadcasting. It turned out that, she did the right thing. Other wise she would have not made it to work on the following day. That was 02/02/2011
I remember the roads were so clear on the way to work. Only vehicles that I saw on the roads were snow plowing trucks. The rest were in the ditch.
I got to the building entrance with inches of snow and one man's footprints (see pic below). Afraid of being alone in the big building, I took off. I learned later (via email) that the entire office was closed.
Got back to the garage, with my crappie fishing gears, I decided to take my baby Runner out for ... a ride, heading south to check out the roads and crappies.
On the way to the honey holes, I took pictures of trucks that were stuck on the big pile of snow off the roads. After counting 49-50 trucks, I stopped taking picture.
Back to the subject, to the OP, our Runners are not much different to those that ran off the road - 4 wheel drive with some advance analog/digital controls. When it comes snow and ice, we (our 4WDs and others ' 2WDs) are almost in the same boat - Ice skating?
I have driven through 8" - 12" of snow without issue, but I have seen cars and trucks ran off the roads when there was only an inch or less of snow on the roads. The main difference was the weather and road conditions. If it's below the freezing point (32F?) and the road has no salts, we would most likely see some vehicles run off the road.
So drive carefully.
I m sorry for such long post
