There has been a car parked on the road outside my house for about 10 days now. It is covered in bird poo (not a problem, generally in this street, so looks like it has been parked somewhere rather more rural for a long time). The tax disc is in date. The car looks pretty empty, there's a bit of rubbish in there and a few cds.
I was thinking of sticking a notice on it saying "Is this car abandoned?" so that if it does belong to someone nearby they might move it.
Is that reasonable do you think?
