This explains exactly nothing to me. There are many cities between Toronto and Montreal (the two largest CMAs in Canada, and about 88% of that driving distance) and I can't imagine why anyone would regularly travel between those two, either. Nor can I imagine why someone would make regular trips between Belleville and Ottawa (very close to the Bakersfield-Merced distance, and two of the larger cities in between).
>If not trains between cities what do you consider public transit?
Subways, light rail, streetcars and buses, all operating within a city. And, yes, trains operating within a CMA. (GO Transit trains from Toronto can get you as far as Kitchener, but as far as I know it's a vastly less popular route than the main Lakeshore lines. From Hamilton to Oshawa is definitely not solid built-up area, but it's pretty dense.)
I can't understand why this would be non-obvious. Maybe there's a cultural difference. Are Americans really so dedicated to urban sprawl that residents of a metropolis with an 7- or even 8-digit population might still require regular intercity travel to go about their lives?
