the car will move.  the center diff will make sure that some torque gets
to the end of the car with traction.

in reality you'll find that so long as a tire or two has some grip
unless you floor it you'll hardly notice that there is any slippery
stuff (unless you are turning, as well).  Remember, it's pretty hard to
have "no friction" at all, though sometimes it seems like it!
