Because we've traveled to major cities I'm fully aware of the times.  We can hop in our car and travel to restaurants, shops etc 20 miles away in 22 minutes while my kids living in places such as Austin and San Francisco can hop in their cars and travel to places 2 or 3 miles away in a half hour.  Plus they get to try and find a parking spot once they're there.  So it's another 10 to 20 minute walk to the actual location.
