If Tesla uses this data, navigation seems to believe this intersection is either NOT a through street or it's a one way street.  Meaning going westward on Panther Creek Parkway, it believes the car cannot turn left (South).  Or going south on Preston Road, it cannot turn left (West) into Panther Creek Parkway.  All routes planned by car navigation will drive pass the spot and do a U-turn.  Or if going westward, any Panther Creek Parkway route will direct the car to go East and then north or south on Hillcrest.
