There are public roads in Hawaii that rental companies won't let you take their cars on as well like the Road to Hana on Maui. Too dangerous - ocean waves eating away at the road, falling rocks and boulder risks, etc. It's only 64 miles but over 600 curves, 59 bridges many of which are single-lane, sweeping elevation changes - it takes a few hours. I see no reason why a private company can't forbid you from using their property on certain public roads.
