said plurality of vehicular cameras comprising a forward-viewing camera located at the equipped vehicle, said forward-viewing camera having a field of view at least forward of the equipped vehicle, said forward-viewing camera operable to capture first image data when the equipped vehicle travels forward;
wherein said forward-viewing camera is located within an interior cabin of the equipped vehicle and is disposed behind a windshield of the equipped vehicle at an in-cabin side of the windshield and views to the exterior of the equipped vehicle through the windshield;
said plurality of vehicular cameras further comprising a rearward-viewing camera located at the equipped vehicle, said rearward-viewing camera having a field of view at least rearward of the equipped vehicle, said rearward-viewing camera operable to capture second image data;
said plurality of vehicular cameras further comprising a driver-side camera located at a driver side of the equipped vehicle, said driver-side camera having a field of view at least sideward and rearward of the equipped vehicle and operable to capture third image data;
said plurality of vehicular cameras further comprising a passenger-side camera located at a passenger side of the equipped vehicle, said passenger-side camera having a field of view at least sideward and rearward of the equipped vehicle and operable to capture fourth image data;
a common image processor for processing first image data captured by said forward-viewing camera and second image data captured by said rearward-viewing camera;
wherein said common image processor processes first image data captured by said forward-viewing camera to detect at least one vehicle present exterior the equipped vehicle;
