    An ordinary car would not be able to go around an unbanked curve of a perfectly smooth road, no matter how the driver turned the wheels.

    i don't understand how i am supposed to interpret this... please help me understand what it is asking

    What must the road provide in order for the velocity of the car to change (ie direction)? Can a perfectly smooth unbanked road provide that? Why or why not?

    By "perfectly smooth" here, the author means "frictionless".
    I apologize for his (unfortunately, traditional) jargon.
