Whether the car is too big or the parking lot is too narrow

I try to park as close to the wall as possible, and my car is actually on the smaller side, but everyone else's cars are so huge…
Every time I go to a supermarket or a large parking lot, I get so worried about door dings ㅠㅠㅋㅋ
I know I should just stop worrying, but I'm honestly surprised by how many people just bang their doors open without any regard for other cars.. If you sit in your car in a parking lot for a while, you'll realize that ignorance is bliss.
