Which is often the case. You tend to hear about the outliers. If a bunch of houses share a common road for example, the maintenance/plowing/etc. of that road has to be divvied up in some way--and it's a reasonable bet that, especially if it's on the longer side, there will be people who object to whatever formula is used. People will also routinely disagree about the degree of maintenance and upkeep that's necessary for any shared facility.
