This is a small angle approximation, right?

Absolutely. There are two orders of power between the observer and the two objects. Typically, 15 degrees is acceptable to use it, or 10+ times the distance of the observer from the two objects. 100+ times the distance is preferable, which is still the case of the car after moving for 2 hours.
