I introduced a couple of typos in the above. The comment in part should read:

"On my Tesla's route navigation, which draws from OpenStreetMap, entering a destination while in the proximity of the drop-off loop at the end of Beeman School Access Road (BSAR) results in the car attempting to exit Beeman GROUNDS by driving down Gardner Terrace. However, there is no actual paved road connection between BSAR and Gardner Terrace -- they're separated by ~20 feet of forest and boulders. It's a footpath that's completely inaccessible for cars."

Thanks again!
