Berlin city center, stupid speed limit of 10 km/h

For some time now, there is a speed limit of 10 km/h in on the minor streets around Berlin's Hackescher Markt, a famous place for Tourists, but also famous for art galleries and craftsmen.

Because my wife has her workshop around this area, I often have to drive through some of these streets. This is not much fun.

Why?
Well, this speed limit is completely useless. Nobody takes it seriously. If you drive 20 km/h you will get much fun. Especially if you have a cab or a parcel service driver behind you. If they can not go at least 50km/h they will start pushing you faster.

I could understand to limit the speed to 30km/h to reduce the amount of traffic and noise for people living there or visiting the area. But I do not see the local people stick to this 10km/h speed limit. Even bicycles would need to go slow, and of course nobody does that. But if you put a limit in place, then please also enforce it. Otherwise this teaches everybody to ignore trafic rules.

I never saw the police measuring around there. Many people would loose their driving license every day if they would. Or the limit would have been changed allready, as many people would have complained.
So please, Berlin City Administration, do something! And I would prefer to see a suitable speed limit.

PS: I just learned that police does measurements at the Gipsstrasse. So be carefull :-)
