The car is a classic symbol of motivation, and reflects whether or not you are feeling autonomous as you move forward in life. If you are driving and the vehicle is out of control, you may be questioning the choices you are making. If you are riding as a passenger, you may not recognize how you are not taking the reins of responsibility for where you are going. You have given power over to the person driving the vehicle and may be needlessly blaming them for failing. If it is a parent driving you, there may be unconscious attitudes or criticisms you have adopted that are holding you back or diminishing your self-esteem.
Vehicle dreams suggest how you feel about your forward movement. If the car is parked, you may have put your sense of direction on hold while you explore new opportunity. The type of vehicle, it's condition, and whether or not you are driving, in control or being driven, will portray your present sense of autonomy. See various types of vehicles under Vehicles and Places of Transportation.
