75 through Northwest Ohio and southern Michigan is pretty tough driving in icy/snowy weather, mainly because the roadway is often elevated slightly above the surrounding terrain, which doesn't have much in the way of trees. Add into that the fact that it's a mostly north-south road in weather that generally runs perpendicular to it, and it can get dicey. I've been blown across both lanes of travel, off the road, and into the ditch on 75.
I can't speak to 75 north of Detroit, as I've never been on it.
