So you would rather he didn't put anything there, and the lorries use the "verge" as part of the "road" and it turns into a rutted, muddy chewed up mess? That is what he is trying to avoid, to make the place look nicer. Try and see it from his viewpoint.
I had this discussion with the highways about what is "the road" and "the verge" and it appears in the case of unfenced land, they can claim the first 3 metres from the edge of the road is "the verge" and therefore part of the highway. If, as we do, you own the land right up to the road, then the solution is to fence it right at the edge od what you own and then it is no longer "the verge"
I have a row of large stones along the edge of my plot at the moment to stop cars and lorries driving onto the grass until I decide how and where I am going to fence the edge
