Granted it's Berlin which has a somewhat peculiar culture but even in the US it seems to be catching on, at least in the large cities.
It seems like the car has lost its cultural appeal as a symbol of freedom & wealth. Now it's just one of many options for transportation.
I cannot wait to see how this could transform cities. Car sharing together with self-driving cars means we need far fewer and they can disappear into a depot when unused. A typical road has four lanes (two for parking, two for driving). You could cut that in half by eliminating parked cars, possibly also eliminate one of the remaining lanes if automation allows for more efficient usage. Suddenly the space available for pedestrians / green / street life has more than doubled, noise and pollutants almost eliminated by electric cars... For dense cities, it could dramatically improve the quality of life.
