Parking is a premium in many neighborhoods and the police know this. It is a low priority and as long as everyone in the area work together and work together it's not an issue.  But all it takes is one resident to ruin the harmony either by hogging all the parking or just have a hair up their butt and complains. So when the police or the abandoned vehicle section get involved, a street where you have 20 cars parked can now only park 5. The rest will park blocks away and now the surrounding residents will wonder where the heck are all these cars coming from! So be very careful what you wish for!
