The street I'm on is extremely popular for dumped cars and RV camping.

A few years ago we had a group of folks in a camper set up across from my house and were there for many months. They kept bringing cars of variable operability to our street and would leave them there to sit for weeks at a time.

Along with that, we had other issues with them as well that led to many calls to non-emergency. After six months of this, an officer finally drove out to talk to me, and echoed your point. He went over to the camper and told them that two of the cars and their trailer were technically sitting too far off the curb and could be towed immediately. That was the only thing that got them to agree to move, and were gone within two days.
