But this expansion is still in the centre of the centre, so to say. Yes, it also covers a few mainly residential blocks. But they're not the cheapest to live in at any rate.
Berlin is still far too car-centric to my taste - even though the number of cars of people is low compared to other German cities (490 cars/1000 adults), there are no large car-free streets or zones, and a lot of 4 and 6 lane steets (many with parking lanes on both sides, added).
I didn't see much use for a car in the Stadt Mitte. It made more sense in outskirt neighborhoods like Frohnhau or when going to the Wannsee or the Tegeler See... </nostalgia> Europeans think a hundred miles is a long way. Americans think a hundred years is a long time.
