Many years ago, a friend of mine--who lived in NYC--insisted that I didn't need a car for my 12 mile commute to work in NJ. He wouldn't give up harping on that topic until I showed him the bus timetables for my area.
The local bus that ran ~1 block from my house would take me south for ~ 9 miles, and then I would have to get off and wait for a westbound bus. The wait for that westbound bus--which ran only on an abbreviated schedule--would have been something on the order of 25 minutes, and in those days there were no bus shelters.
Afer taking that westbound bus, I would then have to walk ~1 mile, along a road with no sidewalks and a lot of traffic.
Both bus rides, plus that long wait and that long walk--in all kinds of weather--meant that I would have to allot ~50 minutes for a commute that took only 18 minutes by car. I finally got him to stop harping on that topic after showing him the reality of the situation.
