The path this note is pointing at is already quite explicitly tagged `motor_vehicle=no`, so I presume it's the driveway to the east that is the concern?

I don't think there is any public access to this driveway either; I know there's a locked gate at the end of it near Three Sisters Drive. The other end down the hill had been connected to the "Legacy Trail" path, but I wonder if there's a gate there too...
