The title says "Travel Distance per person day by main travel mode for urban mobility on all days". That is ambiguous, but suggests that the numbers are actually the share of the travel distance for peoples' main mode, meaning that people who need to travel further in a day tend to have cars, to an overwhelming extent.
That is still a coherent situation in a world where most people don't use cars because their daily travel needs only involve short distances (e.g. because they live in an area where all of their needs are met within a short range).
