I don't get it.

I don't get it. Why is it that a person can back into a parking space almost taking out the cars around them and the grocery cart return but cannot back out of a parking spot to leave. You #1 cannot put your groceries in the back of your car because you have backed all the way up against the cart return. #2 You are so close to one of the cars next to you that your passenger has to climb out the window just to get out of the car. This isn't just a guy thing either. I just don't get it.
