if you look at the aerial imagery; there are two driveways that are here and they've been added with these lines... There are many more driveways in this area but they have not been added to the map, so the lines may not make sense to you.. These lines are useful represent the real world (the goal of OSM) and they allow software (like those that provide) walking directions) that would tell a person that they could walk old lorain road to riveredge road.
