I pull into the driveway between a fence and my house, with not much room to spare. Then the driveway fans out into three spaces: One straight a head, another to the right , and another to the right again. On the far right is a row of hedges where I park. I have no trouble pulling in without hitting the hedges. However when I pull out, I can barely get the back end of the car between the fence and the house without scratching the right front fender on the hedges. Related to this is the question: Is backing up a reciprocal function to going forward? In other words, if I could replicate my steering when backing up (in relation to distance traveled), would the car go over the same path? If the answer is yes, then I just need to improve my driving skills. But I suspect that since the car is wide in relation to the spaces involved, it may not be reciprocal.

The movement IS reciprocal, but the response of the car, in terms of sensitivity to the steering input, is not. Since we do not drive in reverse for any length of time we do not learn the handling characteristics of the car when going backwards.
There is a proof of this: Imagine that the car was a railway truck and there were rails on your drive. The car would follow the same path out as when it went in.
I have watched in amazement at HGV drivers backing into impossible spaces, so it really is all down to practice. But don't worry, I and many others have the same difficulty.

the answer is yes,imagine playing video of a car entering a drive way and play it in reverse ,it will take the same route .
