Motorhomes are permitted to park in designated spaces in my town, next to a grassy area facing the beach. It's a nice spot. If we didn't live here, we would go there.
The car park is shared with car users. In the summer, plenty of them put out chairs and so on, next to their cars. A motorhomer can't do that. Motorhomers can, for example, put their chairs out on the beach, but there isn't a prescribed distance where sitting is or isn't allowed. It's a daft rule.
So if the motorhomer and the car user swapped sitting spaces, so the motorhomer put their chair next to the car; and the car user put their chair next to the motorhome, it seems nobody is doing anything wrong.
Let's make it even sillier. Let's say the motorhomer
uses the car owner's chair beside their van. And the car owner uses the motorhomer's chair next to their car. What if the chairs were the same design? What a calamity! The motorhoming police would be having nightmares, not just about enforcing it, but how to source all the red tape they need.
To get back to being sensible, I'm with
@mariesnowgoose . The real problem is people who leave a mess or damage - it's got nothing to do with the vehicle they are in. And it's frustrating that local authorities, and some members of the public, can't or won't see that.
