I totally agree on the 2020 goal: it seems totally really un-reasonnable to me too. You simply don't change a car-centric population in 5 years!

I commute by bike everyday, 10 km, in a medium city in the french alps. Every single day I encounter a situation where I am concretely in danger. French drivers suck and simply don't care about bike riders.

When you ride a bicycle in Berlin or Tokyo you truly sense what it's like to be actually considered, and it changes all your interface with the city!
