Can sense slow-moving or stationary objects when driving at low speeds. Some may even brake for you to avoid obstacles.
This feature activates at slow speeds and will provide warnings of impending collisions. For some versions, it will brake the car automatically.
What It Does: Uses sensors mounted in the front and or rear bumpers to determine the distance between the car and nearby objects.
What It Does Not Do: It is not as susceptible to low-visibility conditions like fog, snow and rain because it uses radar and sonar technology versus a camera.
