This is fascinating, thanks for posting this link. A quick question = why is Flensburg relevant in the this quote/lyric reference:

"The seminal electronic band Kraftwerk was well ahead of the curve musically, but even the lyrics to their 1981 song "Computerwelt" can seem uncannily prescient. "Interpol and Deutsche Bank, FBI and Scotland Yard, Flensburg and the BKA, they’ve got all our data squirreled away."

Flensburg is just a northern city no?

It is also where the "Kraftfahrt-Bundesamt" is located and keeps track of driving offences. We have a system where for some driving offences (speeding, running over a red light, using a mobile phone while driving) you, in addition to a fine, get penalty points. Accumulating a certain amount of points within a 2 year period may cost you your driver's license. In German this is referred to as "Punkte in Flensburg" (lit. points in Flensburg).

Ah neat, thanks, it is amazing how prescient that Kraftwerk line is.

I am curious what was the general public response to the Malte Spitz's visualization?

Interesting, but I think it makes a pretty bad argument in favor of privacy if you publish your whereabouts of a whole year in a newspaper.

In favor of his own privacy yes. He exposed his location history to inform others that big brother knows this about them too.

He was also a politician, and their expectation of privacy is less than ordinary people anyway (e.g. sex life, earnings, people they meet, donations they do, etc.). So I'm happy he made a case of himself for privacy, demonstrating in parallel that he's not ashamed of his whereabouts.
