I can appreciate what you're trying to say Andy..
But, I don't think that frequency is really the issue. Ohh sure, it matters to the people who already take the bus but to the suburban communter who is used to travelling alone by car more buses just look like more of the same.
For these affluent types, the bus is the 'loser cruiser'.
LRT is something that everybody would try at least once. It's in this initial novelty stage that transit really has a chance to woo suburban households.
And when these people see that they can get to wherever they're going faster and cheaper than they could have by car, that's when the magic happens.
That's just my view, albeit an expensive vision for transit in this city. But, I think it's going to have to take something pretty colossal to shake this town's level of automobile dependence.
