Abstract: A method for adapting driving behavior includes inspecting driving behavior of a motor vehicle (1) travelling consecutively with a road user (2). Consecutive travel is detected by at least one sensor of the motor vehicle (1).

If the predicted position of the road user (2) reveals consecutive travel, the method inspects the driving behavior of the motor vehicle (1) as in the case of consecutive travel detected by the at least one sensor. The method adapts a driving behavior while using few sensors to provide a high level of road safety and/or a high level of driving comfort. Optionally, a human-machine interface may display or report back a virtual representation of the road user in the predicted position to the driver of the motor vehicle.
