I would like to add to that, that this is not true for the country side. At least in Germany. Public transport is pretty much non existent there, e.g. (anecdotal) a part of my family lives in a village with ~4000 inhabitants. To get to the next bigger city there is one bus that goes in the morning and one that goes back in the afternoon. That is it. If you want to go to dinner or visit someone after that, you need a car or go by bike 15km one way.
