> In developing countries this shift has already happened ('distance' to 'time') due to things like traffic jams, inconsistent infrastructure (some routes are longer but faster due to lesser traffic signals or better maintained etc.)

Then I guess Germany has not yet developed. But when talking about places people always specify the distance. Berlin is 584 km away from Munich, not 5 hours and 15 minutes. Talking about time to destination is something I have exclusively seen Americans do. Maybe that's because in the US distance and time are basically the same, since everybody takes the car and drives at the speed limit. But in Germany there is no general speed limit, and you might also decide to take the train or airplane to Berlin (and may people do) at which point talking about time would be confusing at best.
