I took several graphics courses in university, and have built several raytracers in my life, and the ammount of benefit you see from tracing past 3 reflections is fairly tiny.
Realistically, you're going to see the reflection of the environment in the car (or the reflection of the car off of a window) but you're probably not going to see the reflection of the car off of the reflection of the window in a car unless you're looking at a still image.
I doubt most hollywood movies use more than a algorithm that is 6 rays deep, although they probably use a far more advanced algorithm (photon-mapping) for their diffuse lighting.
