Traffic Light Jammer
This traffic light on Invalidenstrasse Berlin takes ages before it switches to green for pedestrians. Additionally it has an antenna sensing the aproaching tramway. In that case it takes even longer before you may cross the street. I want a jammer for that signal! Hmm…what frequency this tramway antenna might run on?

(Yeh, I know. Just we germans would wait for a green light.)
