Pre-covid, we parked our car both in front of the house (blue on diagram), and down the side opposite neighbours house (who has a drive further down.) Occasionally we would get a note asking us not to. No good reason for it as we never parked close enough to the junction to obstruct the view coming out. We ignored it. Other neighbours parked their too and also had notes.
During lockdown some cones appeared (red circles). We weren't going out to work and my car battery died so sat where it was parked in front of our house and so we weren't bothered.
Now most people are back at work we are getting back to the situation on most streets whereby people park where they can get a space and sometimes that is outside our house. Not a problem, but the cones are still there which means that about 3 car spaces are out of use because one anonymous neighbour has decided to cone the area off for their convenience.
If it was the neighbours whose house is opposite the cones, I would kind of get it, but it isn't as we speak to them and they are baffled by it too.
So far, I have not needed to park there. If I do in the coming weeks, would it be unreasonable to move the ones?
