When creating a route that includes private roads, the notification is included in the html_instructions field rather than the warnings array:
- https://maps.googleapis.com/maps/api/directions/json?origin=37.4830854%2C-122.1505874&destination=37.48171%2C-122.15593&mode=driving
- "html_instructions" : "Turn \u003cb\u003eleft\u003c/b\u003e\u003cdiv style=\"font-size:0.9em\"\u003ePartial restricted usage road\u003c/div\u003e"
- "warnings" : []

Rather than parsing the html_instructions field which may change formats in the future, would it be possible to include private roads in the warnings array similar to maps.google.com? (see attached image)
