Hi Bob, a bit of advice to sort these Ignorant BSDS out I had the same prob a year or so ago, first have a word with the person make a not of the date, time, I would also take a few pics with a time dated Digi Camera, also take measurements of how close he / she is to the entrance of your drive, when you are doing the pics try & do it with the person seeing you & if he/she asks if there is a problem tell him/her what the problem is, he/she is obstructing your vision for exiting your drive & there is every possibility there could be an accident because of the van, how close is the van to the corner? get all your facts right before a complaint is made, I have just got in contact with my Insurance because of a person that is doing the same thing but he is directly opp my drive thus causing a problem as I reverse in, I do not expect him to park elsewhere only to use his bloody head, mind you, some of them have brains in the ars.
