In paragraph 2 it says that cars that exsist today aren fully driverless because they alert you in tricky situations, like pulling in and out of driveways, or dealing with complicated traffic issues. Certainly this is just a minor problem compared to the actual driving part, and is planned to be figured out in the near future.
