I'm in Michigan as well; got dumped on pretty good. It took me an hour to clear our 16' x 85' driveway this morning with a good sized snowblower. Even then, I don't think our minivan would do well on the streets. I have a fullsize 4x4 and that's the only reason I even attempted to drive to work. Our neighborhood wasn't too bad, thanks to residential snow plows dragging their plows, but I hit some pretty deep snow when I hit the intersection at the first main road. That's where I'm sure the van would've got hung up. As it was, even with my truck, I had to back up and try again, after I sank when I stopped.
FWIW, I guesstimate that the snow was about 17-20" deep in the middle of our driveway, between the house and neighbors garage. It was about 12-"15" everywhere else.
