The traffic data is not as good as it appears. It is completely closed, only given to police and goverment agencies. No API, no numerical values for speed (only 5 ‘color codes’ that are relative to location, so are almost useles) and numerical data is not given even to academics. I spent almost a whole month trying to get actual useful data for academic purposes, but Google really went out in their path to make it impossible.
It has the potential to be an excellent tool: crowsourced real-time data, access to historical data and it is incredibly fine-grained, improving over goverment data (at least in my city) by a 10 or 100x factor. But no, it had to be yet another Google’s tool for spying on people, not giving it away and sell it to police.
Ne Obliviscaris - Portal of I. A progressive extreme metal. If you want to give it a shot, listen And Plague Flowers The Kaleidoscope, to see if it is for you.
Honorific mention to Nirvana - All of us. This is not Kurt Kobain’s Nirvana, but another band called that way back from 1967. Amazing soft psychedelic rock. The band’s history is quite interesting as well, including a lawsuit against Kurt Kobain’s Nirvana, and then also trying to cash out of KB’s Nirvana popularity by launching a new album after several years of breaking up, in order to profit from confused customers. Then, last year they launched a new album, after 50+ years of their original break up (which I really enjoy as well).
