La distancia de detención, ¿de qué depende?

Reaction time is the time from when the driver sees an obstacle until they react. This time varies with the driver's physical and mental state, never with speed or road conditions. Although it may seem that our reaction to an obstacle or unexpected situation should be instant, a driver's average reaction time is about 0.75 seconds. Reaction distance is the number of metres the vehicle travels during that reaction time. This distance depends on the reaction time and the speed (the higher the speed, the more metres travelled in the same time). Braking distance is the distance the vehicle travels from when the driver brakes until the vehicle stops. It depends on speed, the vehicle's mass and load, the condition of the vehicle, road conditions and the weather (rain x2, snow or ice x10). Stopping distance is the reaction distance plus the braking distance. So stopping distance is the distance the vehicle travels from when the driver perceives a danger until the vehicle comes to a complete stop.
