  Speed determines time to stop including stopping distance and reaction time. For every second of reaction time per 10kmph you add about 4 meters of distance travelled before you even hit the brakes. So best case if you aren't looking at your HVAC, at 50kmph you will start the stopping process in about 28 meters, and at 60kmph it will be 33.3m and take longer to stop once you hit the pegs. Doesn't sound like heaps but that is actually your margin for error, just 4m. If something jumps out in front of you at 28 meters away, at 50 you will have had 4 meters to stop, which modern cars can do, and at 60 you will hit them at the full 60kmph. The Australian government has some great road safety clips on the subject, I might try and find them.
