On the one hand I can kinda feel the pain of the homeowners. When my neighbor recently had a yard sale, I basically had to sit in my driveway telling people to not block it in case I had to get out. Some would actually try and argue with me. So, I know how selfish and stupid people can be sometimes.
But, selfish and stupid works both ways. The homeowners near there can't deny people right of way on public streets. They can't put up fake signs/paint. This isn't right either. The best you can do is just try and keep the idiots off your own property.
