Honestly this is absurd. These death machines shouldn't be legal in europe. That thing doesn't even fit in the parking space, even though the parking lot has the biggest spaces in the whole city. The Golf Polo is so small in comparison, it could even hide in front of the engine hood of the truck.
EDIT: It's a Polo and not a Golf, I don't know my cars, sorry for that!
In my part of the world cops have written warning to those who report these people because "taking a photo of their license plate is a violation of their privacy".
That's not what a Karen is at all. A Karen reports someone for doing things that arent a crime and that's why they're unreasonable (often against people of color). Like when that woman called the cops on that dude leaving his own home.
Also parking on the pavement is dangerous and reduces accessibility for other people navigating that. So yes, report them.
