Systems and methods are provided for detecting and responding to cut in vehicles, and for navigating while taking into consideration an altruistic behavior parameter. In one implementation, a vehicle cut in detection and response system for a host vehicle system may include a data interface and at least one processing device. The at least one processing device may be programmed to receive, via the data interface, a plurality of images from at least one image capture device associated with the host vehicle; identify, in the plurality of images, a representation of a target vehicle traveling in a first lane different from a second lane in which the host vehicle is traveling; identify, based on analysis of the plurality of images, at least one indicator that the target vehicle will change from the first lane to the second lane; detect whether at least one predetermined cut in sensitivity change factor is present in an environment of the host vehicle; cause a first navigational response in the host vehicle based on the identification of the at least one indicator and based on a value associated with a first cut in sensitivity parameter where no predetermined cut in sensitivity change factor is detected; and cause a second navigational response in the host vehicle based on the identification of the at least one indicator and based on a value associated with a second cut in sensitivity parameter where the at least one predetermined cut in sensitivity change factor is detected, the second cut in sensitivity parameter being different from the first cut in sensitivity parameter.
