New car people hitting it with their doors

So I got a new car about a year ago, and I've noticed ever since I got a nicer car people don't care if they hit it with their doors when I'm sitting in my car. It's starting to piss me off because it's just lazy and blatantly rude. I usually don't say anything but it's getting harder to not say anything. 9/10 they don't apologized. It's only a kia forte but I worked hard for it. And it's not because I park like an ass hole, if i do park bad I fix it.

How do you deal with this??
