Usain Bolt Disqualified for false start!

I saw a good new idea for the new false start rule. Just let the sprinters leave "around" the same time and if someone leaves early, add some 1/100 seconds more into the time of the runner. With the modern technology, that should be moderately fast.

With modern technology, you can track each and every one of them and get their exact times even if they all leave at different times. An entire sport is based around that general idea, sailing. Boats all start at different times based on class and size, due to the fact that boats capable of destroying any smaller boat's time compete together with them.
