The driverless car will know when to take control, where it is located and which direction to drive in.
To detect which landing strip it has been parked at, the document says the car could activate a GPS (global positioning system) receiver to find its rough location and then use its sensors to detect trees, foliage or other known landmarks to determine its exact position.
The document describes using two sets of sensors. The first identifies a "landing strip" when the vehicle stops. This then triggers the second set which receives data informing the machine where it is positioned and where it should go.
Google says the landing strip could simply be a mark on the ground, a sign on a wall, or lines or arrows showing where the vehicle should be parked.
