If I built a house or business in RL my driveway wouldn't stop at the edge of my property, it would extend onto the road allowance and connect to the paved portion of the roadway. That's what I also do in SL. I don't encroach on the PAVED surface in any way, but omg yes, my rooted on my own land prim is over the boundary line. I'd sincerely hope the Lindens have better things to do with their time than return prims that only add value and continuity to a scene.
