Dreaming about car is read less as a fixed meaning and more as a lens on what it stirs in you. Commonly read as control over one’s direction in life — who is driving, and how. What it means for you depends on the feeling it carried and what’s happening in your waking life.
These are interpretive lenses, not facts — your own feeling in the dream is the better guide.
