I find a spot where I can pull through. No matter what you think, backing into a spot takes more time then pulling forward into a spot. I saw a woman that pulled past a spot preparing to back into it and someone behind her took the spot. I just laughed. It did appear she was not taking the spot. She was giving the person that "took" her spot a talking to as I walked by and I just said "looked to me too that you didn't want the spot" and kept walking

.
She should have used her blinker, indicating that she was planning to take that spot. If she didn't then she has no reason to be upset at the person who "took" her spot. lol
I find it easier to park further away and just "pull through" to the other side. That way I don't have to back up while parking or when leaving.
I will back into my driveway when I have a lot of stuff to unload, but if there is a car behind me as I approach my driveway, I'll pull over and let them pass before backing in.
This is my thinking, I'd rather pull thru then back in and when I do back into my driveway I have plenty of space to get in with one try. Our street is very small and slow so it's rare that someone is behind me when I'm planning to back in but when it happens I just pull over and let them pass and then back in.
I always back in. It takes seconds to do and is much more convenient for me. I don't understand why it bugs people so much.
It doesn't bug me at all, unless it's someone who takes forever to get into the spot. But then again I wouldn't wait, if they need to "fix" their parking I normally just wait until they are in the spot enough for me to get by and then I go around them, it's rare that I'm sitting and waiting for a long time while someone parks.
Because people have to wait for you to get backed in before they can move on and park themselves.
Because if you pass a spot because you are going to back in, the person behind you (as well as everyone behind them) will have to back up to accomodate your backing in.
Inconvenience to other people should be considered.
Again, someone who is backing in should use a blinker to indicate they are taking that spot, and they should be experienced enough to not have to pull in and out multiple times. You should be leaving enough room between you and the car ahead of you that if they do decide to back in they have room to do so. Also, no one should have to wait, parking lots should be large enough to accommodate the person backing in and the person behind them having room to go around.....
DBF will back in sometimes but we normally just pull into our spots or pull thru. I have drive a minivan, it's not easy to back it into a spot, it's much easier to back it out of a spot. He has a sedan, it's very easy to back into a spot but we rarely do it.
