This is actually incorrect. When you ask a German how far away another city is, their first question will be: "What kind of car do you drive?"
The biggest difference is that in Germany, the speeds are more sustained. In the US, cars generally drive in whatever lane they feel like, so your speed is constantly changing. So even a difference of 180 vs 140 will be significant. (and it could easily be 200 instead of 120).
