The movement will be spread over the given number of seconds so you won't see much if you set this to '1'. Values of ~ 3 are recommended and you will then see the vehicle change more smoothly (position and angle will vary over time).How smooth exactly, also depends on the simulation step length (option --step-length). Try tracking a vehicle (right-click vehicle, 'start tracking') and set a delay in the gui to follow its movements.
