Technically yes, but it would be easier to get some fishing line or something to make them move in real life.
If you must move them in AE, you will need images of the cars at every angle of each shot you'll be using. You'll have to use a good storyboard and plan your shots out well. You can't have the cars turning in any of the shots except directly overhead without having to deal with faking the distortion or something to keep the perspective right.
