It won’t happen anytime soon, because the mapping systems are extremely flawed and will remain so indefinitely. There are already too many instances where the GPS systems have sent vehicles down railroad tracks only to have the vehicle occupants killed in collisions with trains. Then there are the people, animals, and debris which obstruct the paths of the vehicles in ways which will result in the vehicle colliding with the obstructions, skidding off the roadway to avoid the obstructions, and assorted other mishaps the automated controls cannot cope with as well as the human driver.
