The average one-way LA commute is 29 minutes. This compares with 45 minutes for the UK (the whole country, not just urban areas) and 38 minutes for the EU. A variety of sources suggests that the median commuting time in Japan is greater than 30 minutes and the average is longer (because of skewed data).
European cities are great for vacations, and wealthy people in such cities can live in places that allow them to walk to work. But for average people, LA is a easier place to get around.
