This was shot at Lausanne during rush hour and is indeed all downhill to the lake. Apparently this was a performance piece which demonstrates the simplicity, fluidity, efficiency and freedom of cycling compared to the act of driving which is described as a act of making war.
"Rouler en voiture, c'est faire la guerre." était la phrase de base.
translates as:
"Driving by car is making war." was the basic sentence.
As a statement it's quite nice, but it's hard to get past the fact that he's riding like a total nutter, albiet with some good skills. I wouldn't be stopping at traffic lights without my kit on if it were me though.
You've got to love the cycle activists though...
