8. The vehicle navigation system of claim 1 , wherein the predetermined cut in sensitivity change factor includes a lane shift ahead of the target vehicle.
9. The vehicle navigation system of claim 8 , wherein the lane shift is detected based on analysis of the plurality of images.
10. The vehicle navigation system of claim 8 , wherein the lane shift is determined based on map data.
11. The vehicle navigation system of claim 1 , wherein the predetermined cut in sensitivity change factor includes a geographical area in which the target vehicle is located.
12. The vehicle navigation system of claim 11 , wherein the geographical area is identified based on analysis of the plurality of images.
13. The vehicle navigation system of claim 1 , wherein the navigational response in the host vehicle includes alter a speed of the vehicle.
14. A computer-implemented method for detecting and responding to a cut-in by a target vehicle, the method comprising:
receiving image data captured by at least one image capture device of a host vehicle, the image data being representative of an environment of the host vehicle;
identifying, based on analysis of the image data, a target vehicle traveling in a lane adjacent to a lane in which the host vehicle is traveling;
determining, based on analysis of the image data, that a predetermined cut in sensitivity change factor is present in an environment of the host vehicle, wherein determining that the predetermined cut in sensitivity change factor is present comprises:
tracking a representation of at least one feature in the environment of the host vehicle across multiple image frames, and
generating measurements of the at least one feature using one or more time-based observations; and
based on the determination that the predetermined cut in sensitivity change factor is present, causing a navigational response in the host vehicle.
15. The computer-implemented method of claim 14 , wherein the navigational response in the host vehicle is caused independent of a detection of a navigational change by the target vehicle.
16. The computer-implemented method of claim 14 , wherein the predetermined cut in sensitivity change factor includes an end of lane condition.
