We are in the middle of a building project. Drive is partly dug up so we are parking on the street in front of our own house but sometimes over the dropped kerb to our drive if DH is unloading pipework etc. Our plot is wide enough that we can get both cars in front of house and leave the drive clear for deliveries.
The old boy who lives next door (drive side) is the only house that has no off road parking so parks his car on the street outside his house. We get on really well with him
For a while he was poorly so his relatives were picking his up/dropping him off and parking across our drive. This wasn't an issue as it clearly was to minimise him having to walk and if anything came building wise they would only be there a short while before it was moved.
Since then his relatives/friends have continued to block our driveway. For context he has family visit several times per day for anything from 15 minutes to a few hours. There's always space to park the other side of his car or opposite without blocking anyone else's access.
DH gets naffed off as sometimes he gets back with a car full of pipework and can't unload it straight onto our drive.
Mostly it's only an issue if we are having stuff delivered - today we are having some stone delivered from the builders merchant.
This morning a car pulled up with two ladies in who pulled straight across the drive and went in for an hour. I popped a note on the windscreen 'please don't block this drive' which I haven't done before. When I went to put the bin out they were outside and complaining that I'm 'not using the drive anyway'. They weren't being aggressive but seemed very put out.
I explained that I have a delivery coming and need access and they said if I knocked they'd have moved it for the delivery.
AIBU to expect people to not block the dropped kerb where my driveway is even though it's not being used for parking? I don't see why I should have to go and knock when they shouldn't be parked there.
