Ow... That is disturbing. Very disturbing.
A little number that I figured out recently... Speed in MPH is really meaningless to a pedestrian, or in any urban situation. The measure that matters to people on foot is fps. Feet per second.
All you need to remember is 1.466.
That's the equivalent of 1 mph expressed in fps. Round up to 1.5 for close enough.
e.g. multiply by 30, and in one second a car will travel 45 feet. A pedestrian at 3mph can travel 4.5 feet in the same time. Not even the width of a car.
There's another ad in the same UK series, equally graphic, that makes the same point in terms of survival rates: http://www.youtube.com/watch?v=Cvja-PA5Egc&feature=related
