I'm in Berlin for week, enjoying a city that many friends said is definitely worth visiting. Well, they were right :)
The first thing I noticed was the traffic. I took my car to Berlin and the first day (without a good map) I got lost all the time. Totally frustrating since I normally navigate in new cities without any problems. Normally, when I miss a turn, I just take the next one and make sure to go left and right one more to get back to the right road. This strategy completely breaks down in Berlin since almost no road is straight (nor circular, for that matter).
