Around the year 2000+/-2 that was my daily experience on the track from Hagen in Westfalen(near Dortmund) to Cologne or Düsseldorf. When it went over the Autobahn there was always gridlock. I noticed that mostly out of the corners of my eyes, while reading Tipler's Physics, Stryer's Biochemistry, Albert's Molecular Biology of the Cell, or other sciency stuff like that, comfortably munching something and sipping coffee. Hopping into some bus, tram, subway for another 10 to 20 minutes, arriving relaxed and fit.
