As I’ve said, you’re underestimating the enormoty of the problem and the distances we travel for normal things.

Maybe, but on the other hand, some villages are so small here (couple of hundreds of residents), but they have rather frequent (hourly or more) transit. Furthermore, suburbs are definitively dense enough for buses and bikes. In between, investments for transit are needed. And sure there are areas where it is probably not feasible to do so, but only few people are affected.
