I live on a a road that can be quite tight in places, few houses without drives hence not much parking space. We have a drive space for one car, then we park the other on the front (which is a public road - first come first served) but generally we’re parked there. Recently we’ve been having a bit of trouble from a house down the road with two cars and no driveway, left notes on our car and knocked on asking us to block each other in rather than taking up an extra space, also been quite aggressive towards me. It’s a bit of a faff if we do as we have to let each other out when the other needs to go out etc. AIBU by not blocking each other in and letting them have the space? I have to say I find the whole situation a bit pathetic. There is also parking available the other side of their house that’s where there is always room but it’s further away for them (extra minute walk) than being outside ours.
