Took me a while to understand the middle graph but maybe my eye is not used to it.
Do I understand that correctly that public transport is actually not that bad compared to a car (as the red dots cluster not so far from the car dots)?
Another question, is parking possibilities etc. taken into account when talking about car accessibility etc.? In Tel Aviv for example, the parking situation is so bad (really bad) that many people are switching to electronic bikes in the past 2-3 years.
