We once had a small white van `dumped` outside our house,It was a bit of wreck and not taxed. We contacted the police but they said as it wasnt illegally parked they could only report to the DVLA about it not being taxed,who would contact the owner and allow him a time to get it taxed etc. which would probably end up being weeks before anything was done. The police told us if it had been on double yellow lines, they could have it removed. Well, it just so happens that as we live near the end of the road, towards the end, there are double yellow lines. The back doors of the van were open, so my husband got in and took off the handbrake, and then with my son, pushed it so it was just on the lines but safely parked. We didnt even have to ring the police again which we thought we would do after a day or two ,because the van was towed away the next day, much to the relief of all our neighbours.
