Dinged someones car door and drove away

[Dragonfirestone]

I was out shopping with my friend and baby, she had driven us in her car. at a carpark, when we returned to our parking space the car beside us had parked over the line into our space on the side with the car seat, thinking I could still get my child in I opened our car door and unfortunately it did a small dinge, when I checked the other car there did not appear to be any dents but the smallest dot of white paint from my friends car was there. My friend said not to worry and she backed out of the space to let us get in safely (something we should have done from the start). There was no one in the other car and my friend drove off but now im worried we'll get in trouble or that someone will have saw us and report it? AIBU for worrying, friend doesn't seem bothered!

I’ve re-read the original post and didn’t realise it was only a fleck!

In my case, the part of the bumper was hanging down on open side and some kind of van had scraped right down to the metal right the way across. It was bad on two sides so we still have no idea what happened! One panel had to be replaced entirely.

It's hardly the end of the world.

In car rental, a scratch is classed as something deep enough to get a fingernail into. Not a tiny fleck of paint.

The smallest fleck of paint and ppl here would be phoning police and insurance companies?
Would most ppl even notice this? No wonder insurance is ever increasing and you can't get through to the police when you need them

I strongly disagree. Are you really suggesting that, in parking a vehicle on a public road, you've also additionally 'claimed' the full width of your open door as well - so there's another three-foot width of empty road that just can't be used by any other road-user?

That's kind of like saying that an eight-foot wide pavement isn't ever safe or sufficient for two people to pass by on, just in case one of them randomly swings their arms out fully without looking!

What? It’s even part of the hazard perception test to look ahead and be aware of upcoming things like this! You would fail if you don’t look out for them. It’s like a pedestrian stepping into the road. You need to watch out.
If you’re driving so close you take someone's door off then you weren’t paying attention.

Yes, you should be aware of the potential hazard of somebody opening the door of a parked car without looking first, but that's more to protect yourself rather than because they are in the right.

The way traffic works is that (like it or not) motor vehicles that are moving have the priority over those that aren't and over pedestrians; with the expectation that the onus is on pedestrians not to just step out without looking, and also on stationary cars and traffic approaching from minor roads/side streets not to pull on to a more major road without looking and waiting for a suitable gap.

Of course it's incumbent on all motorists and road-users to be very alert at all times - which would be nigh on impossible if you had to crawl along peering inside every single parked car and allowing for somebody flinging their door open without looking.

No they don't!!

Ffs! 🤦‍♀️

Given that we are talking about a complete non-incident with no damage and nothing to report then everyone should be doing what the OP did and walking away.
