I wish someone would deal with the car that has been abandoned by us. We looked it up and the tax expires soon, so we could report it then. I'm not sure if the police can get a ticket, but they are supposed to obey the rules unless they are actually dealing with a crime.
I know horse riders have POLITE vests too. There are too many idiots on the road, but the police cannot be everywhere.
We have at least two levels of car criminals here. The ones that steal cars and the ones that strip the parts bare without moving the cars. There a few car chasses dotted around the place here. Now and again the scrap metal people come for them (to strip the rest I guess), but it's a big problem. Some of those cars abandoned in your town were probably stolen from London.
