Why can't I park correctly in spaces?

Whenever I need to park in a space at a parking lot, I have to park away from other cars and pull through. If i'm not able to pull through, you bet i'm slanted and taking up part of a second space or very close to it. I've practiced forever and just can't get the hang of it! Everyone says it will come with practice, even my driving instructor when I told him I needed help with it 3 years ago! (He refused to help me) So now, I go to empty lots in my free time and try to park… Still no improvement! I have also tried many different techniques and tips from my family and friends. I feel so dumb when I'm with someone else and they can just whip right into the space no matter what. Maybe I should just stick to pulling through spaces in the back. Any advice or tips for me? I've been driving for 3 years and I have a honda civic sedan, however I have tried to park countless different cars. This one is the easiest for me.

Uh, that makes you normal. Take a drive through any parking lot and about half or more of the cars are slanted, or over the line, hanging out. Apparently it's a very common problem, and most people just give up trying to park well.

Adjust your door mirrors down so you can see the white line of the parking space and you can follow the line as you park, it will make it a lot easier.

You would be surprised how many people have this problem… But do not admit it. It should be easier with a small car like a Civic, but…

I find it easier if you have a car parked behind you, so you have something to aim at. And if you adjust your mirror down slightly, you should be able to see the curb. And when all else fails, it looks like you can buy cars that park them selves. No sweat.

You know what? I'm the same and I have been driving for 21 years.

I always try to drive through, or find two spaces adjacent so I can steer across the empty space.

The biggest problem is that you can't see the lines when you're actually IN the space, so you're trying to park relative to other cars, which may not be perfectly aligned in the first place. At your tightest turning circle you're also permanently worried about catching the corner of another car.

If you really want to get good at it, I'm told, go to an abandoned lot (or a normal lot outside of opening hours), with some large cardboard shipping boxes that you can use to simulate other cars without the risk of damage. Practice until the cows come home. This also works for parallel parking if you can find a quiet road. It's not just about practicing, it's the freedom to make mistakes without damaging other cars or annoying other drivers.

Or, get a car with parking sensors.

The reality is that most people don't bother because it's rarely necessary to park extremely accurately on your first attempt at getting into a space. As long as you're wholly within the space and not blocking in other cars it's fine. Get out, look, and adjust if you need to. Let other people be the parking masters who can screech and swerve into a space with 1cm accuracy.

Are you following the procedure correctly? If you don't have the instruction manual from your local DMV yet, get one and check to see if you are lining up correctly.
