The first year I lived in Albany, back when a RWD Impala with studded retreads on the rear wheels only was the best winter car, I was waiting for the light on Hudson and Lark. The light turned, red, then green, red,green, red, green, nobody moved. So I get out of my car and walk up the little hill and there's a guy there spinning his wheels but he can't move, until another guy and I push him through. Then the guy behind him drives to the exact same spot where the first guy got stuck and stops. So we wait there and push him through. Then the guy who was helping me push got back in his car, goes to the exact spot where he just saw two other guys get stuck and he stops. So two of us push him through and as soon as I get back in my car, the guy behind me blows his horn because apparently he wants me to move up to the exact same spot where he just saw three cars get stuck!
The point is that people are idiots and even in Upstate NY, no one knows the first thing about driving in the snow. You shouldn't even think about it, you should just do what I tell you.
