I fully agree with having Walter Grey use transit and only transit for one whole month.
Have him keep a log of the number of times the bus is late/doesn't show up and how out of the way he had to travel just to get somewhere simple.
Also, how much time of his valuable time he wastes waiting for improperly timed "connections" and walking to and from the bus to his house/office/grocery store.
Maybe this will encourage him to push harder for a decent transit system in this city instead of the joke of one that we have now.
