A former neighbor of mine had a very similar problem of cars careening around the sharp corner and ending up next to his porch, chewing up his lawn/garden in the process. One truck demolished the vegetable stand he had out front. He wanted to put up a border wall (stone wall) all along his property, which he had to fight town hall for permission. He told them if they wouldn't permit it, he'd start suing the town for recompense since they haven't done a damn thing to stop the speeding traffic. He ended up with a border wall.
