It also unlocks and won't lock at about 20mph so you don't get into the rear wheel drive locked rear end fishtail suicide run if you hit ice at speed. It is not going to help you turn, steer, or brake, but it will let you keep going in worse conditions without getting stuck.

I get this but it doesn't address why duals perform worse than singles in ice/snow/mud.
