The law recognizes reality; a motor vehicle, even one driven by a "perfect" driver, has far fewer degrees of freedom in any given situation than a pedestrian. The vehicle has momentum, limitations on the braking force that can be applied to this momentum, limitations on the ability of the steering system to change the direction that the vehicle mass is traveling in, and sensory limitations for the driver that can decrease the reaction time available. A pedestrian can not move as fast or as far in reaction to such a situation, but they can change direction of travel far more quickly and have a better ability to hear or see the oncoming vehicle.
