Bike route on Google Maps

Just discovered today the “bike option” in Google maps. Looks like they read a previous post about the fact that my route on their maps was not accurate, due to the many streets in Basel you may take in one way with your bike, but not with a car (forbidden). This map is quite accurate on the road I take with my bike. The only limitation : as France is not covered (yet ? not that many bikers there ?!), I had to enter only my way in Switzerland to get it work, and to put the starting point in the first Swiss village I enter into.
