Police are visiting someone on my street for some reason and have parked behind me in my very long narrow drive. Haven't asked if they can park there. Lots of space on the road to park however they would be on double yellows. If I needed to go anywhere, I wouldn't be able to move. No idea which house they're in. I need to go out in 35 minutes for a flu jab appointment. I know they could be dealing with a serious emergency but no idea why they're parked on my drive! WIBU to drive very slowly backwards and gently nudge their car off my drive? (Only kidding). Slightly miffed. Should I try and find them and ask them to move?
