I do live close to a small patch of green space and mine and the next house are the last two on our side of the road with a driveway. I frequently get delivery men and people's visitors parking either fully or partly over my drive and it can be very inconvenient as sometimes it's a squeeze getting on. Part of my driveway is a lowered kerb and part is no lowered kerb so depending on how they have parked I am not prepared to bump up my kerb and over the small grass verge that is there. I am getting increasingly annoyed as today one of next doors visitors where all over the lowered section of my driveway where I access my drive and I wasn't going to ruin my tyres by trying to bump up the kerb. How should I tackle this.
