A guy does this down the road from me, i dont give a frig....
Doesnt affect me in anyway, he doesnt park over my drive, sometimes he puts them outside my house. Fair play to him. Its a busy road so he does well. I dont own the road so i cant moan at him. As long as he isnt over your drive, or interfering in your property in any way shape or form i shouldnt bother mate. If your mate has a problem then let him sort it himself....
