Actually it does do the trick, Fons doesn't understand the british turn of
phrase: Jon is not implying an attempt to win the 2010 Tour de France
with his contraption, he is going to have fun on the way to work so I am sure
he can extract acceleration (from traffic lights, Fons, he doesn't actually want
to be the King of the Mountains or anything, not even give or take 5%) based
on the rate of change of a signal.
