Hi Jhumki

The frictionless surface means that there is no horizontal component of
force of the car on the ice or of the ice on the car.

So the car will not move on the frictionless ice surface due to the
rotation of its wheels.

(Tongue in cheek: the exhaust gas from the muffler will however act like a
rocket engine and propel the car.)
