Nowhere in the article does it say that it was on stands for long. Only that the vehicle had been on the road for "a while". What if the guy doesnt have a driveway? Is he not supposed to remove the wheels for whatever reason? The vehicle wasnt ilegal. It was insured, taxed etc. no double yellow lines....
Im sorry but if i was in a position where i didnt have a driveway and i needed to work on the wheels for a day or two, i would be very angry indeed if someone called the police.
Some people need to get a grip on reality. We dont all have big driveways/garages/yards etc.
