Method and device in a motor vehicle for an automatic drive

The invention relates to a method and device in a motor vehicle for an automatic drive. The invention relates to a method in a motor vehicle (50) for an automatic drive, having the following steps: detecting additional motor vehicles in the surroundings (9) of the motor vehicle (50) by means of at least one sensor system (2), detecting and identifying lanes (30, 31) by means of the at least one sensor system (2), assigning the detected additional motor vehicles (51, 52) to the detected lanes (30, 31) by means of a controller (3), and identifying and evaluating an intention to pass (21) of another motor vehicle (51) by means of a pass assistance device (4), and if an intention to pass (21) has been identified: calculating a total use (84) of a possible lane change (20) by means of a predictive device (5), adapting a drive behavior of the motor vehicle (50) by means of the controller (3), wherein the possible lane change (20) is carried out if the calculated total use (84) reaches or exceeds a specified total u
