Maybe other city bus systems operate in the same way. But it was news to me to learn that in London when buses get too far behind schedule or bunched together, they resolve the situation by stopping one of the buses mid route. Then they tell everyone to get off and the bus heads to some different place on the route. Then the passengers are left to figure out their own way–grab a cab, walk, or wait for the next bus and hope it takes you all the way. It’s only happened to me once.
