Are they the Google Earth satellite pictures or the Google Map road level van pictures? If the former there’s no problem because nothing traverse the private road. The later depends on how private road is, is it marked, is it gated, or do people just know.
It’s Street View. Even the school bus is only allowed on the county road and is not allowed on the private roads. All sudivisions within the county are privately owned. Everyone locally just knows this but outsiders wouldn’t. One would “ass u me” a company such as google would have sense (yes, I know) enough to ask where they are allowed and not allowed before they do this. But then, they’re google and have more money to fight it in court than individuals.
