When they are parallel, the automobile has a positive acceleration (it is speeding up). When they are antiparallel (I assume you mean at 180 degrees to each other but in the opposite direction), the automobile has a negative acceleration (it is slowing down). When they are perpendicular they have no effect on each other, therefore the car has a constant velocity.
