A fairly serious oops

Our Park City neighborhood has about 40 condos and 30 single family home lots. Most of the lots are built on, but a few of the remaining ones have recently been sold and construction is starting.  What you see below, isn't that.

This is what happens when someone buys the lot next door and has it surveyed, only to discover that you built your driveway and retaining wall a few feet onto their lot.  You have to tear down the wall, cut back your driveway, and rebuild the wall. Ignoring the expense, I wonder how long it will be before someone backs out of the garage and goes over the edge. Can you say 11-point turn?
