Yes, yes please. Is it their front lawn? As in - they own the land? And they aren't causing any harm or damage to anyone, other than the fact that you don't like it? You mentioned "property value loss" in another comment - that's not a thing. Certainly not due to a car parked on someone's lawn.
Again, I find your intention to get into other people's business just.....strange.
It's not me. It's a community which agreed on a guideline, standard, by-law, etc.

No, it actually is. Demand will suffer in locations which are unkept and trashy. I would not buy a property next to a home that had cars parked on the front lawn. I would not want to live next to someone who thinks that's appropriate and most people would agree with me.
There's a reason we stage homes when selling - we want them to be as attractive as possible. The surrounding area, if nice, will add to the value because people want to live in nice places and around nice people.
I never said it's approporiate. I wouldn't want to live next to such house either. But I find it unacceptable that you would like to regulate that away, just like I don't think it's acceptable to regulate whether someone can hang their laundry outside or not. It's a uniquely American fetishism with defining freedom as "freedom to tell others what they can or cannot do". There's a reason HOAs exist pretty much only there and hardly anywhere else. I might find the sight of my neighbour's car unappealing - but you're the one who wants to regulate what they can or cannot do with it.
