Commute vs driving?
> even this activity adds more mileage to your car.
Why should you care about that?
Things like: going grocery shopping, going to sports/hobbies activities, entertainment, going out to restaurants and bars, meeting friends at parks, etc.
So I did something else: dropped random points inside the cities and plotted routes between them using biking, transit, or cars. In every city I tested (even Berlin!), cars win. And often by 3-5 _times_.
It's understandable, transit is optimized towards traveling to a small number of destinations (typically Downtowns) and lateral travel is often hard.
To try it out I just plotted a simple route from Schöneberg to Mauerpark, it takes ~42 min with transit, ~28 min with a car. With a car you need to find parking (and pay for parking). The same route is ~32 min on a bike.
From Charlottenburg to Lichtenberg (cross city) it's around ~42 min on a car, ~1h10m with transit + walk, or ~1h on a bike. Again, without factoring in times for parking, etc.
Those car trips are estimates with no traffic on a Saturday noon, any other time with more traffic and these estimates should get ~20-30% longer.
