> Standing at a street corner I was shocked that no one jaywalked. There wasn’t a car in sight, yet Germans young and old stood there obediently, waiting for the green walk signal.
I am from Berlin and I jaywalk all the time :) I think people who were actually raised in Berlin are very likely to jaywalk. Looking as to how you visited ITB I suppose many people you've seen were not originally from Berlin (also many startup founders are not originally from Berlin but from all over Germany)
