The system includes an on-board sensor of the host vehicle to detect presence of a preceding vehicle, wireless communication circuitry to establish wireless communication with a remote vehicle, and processing circuitry to detect existence of a slow remote vehicle ahead of the host vehicle, track an immediately preceding vehicle ahead of the host vehicle, confirm that the slow remote vehicle is affecting the host vehicle's lane speed of traffic by detecting that the immediately preceding vehicle is decelerating. When it is determined that, that the remote vehicle is sow, display an information message indicating the existence of the slow remote vehicle, and output, when the remote vehicle is slow and the preceding vehicle is decelerating, the collision warning as an audio sound and a visual message.
