Or to put it a bit more bluntly, based on this chart[1] of typical stopping distances versus speed, you can come to a stop in 53m if you're going 80km/h.

If instead you're going 100km/h, your car will be still be doing over 60km/h after 53m...

Obviously the exact numbers will vary based on car and conditions, but the point stands about just how much things change when you're speeding.
