Maybe once we have the problems, people will accept the solution

We need to make driving suck so much that people would rather take the bus.

Or make the bus suck less. Curbed bus lanes with fat fines for violators would do more to change urban America than anything else; a de facto revival of the streetcar. Why drive through the gridlock at 7mph when the bus is going 35mph right past you?

It would certainly be cheaper than anything that is rail based.

It's not "making" driving suck, it's allowing driving to suck as a result of market forces. We could stop forcing restrictions on property owners that prevent the natural, market-driven move to mass transit as density increases.

This but unironically.

densify portland -> improve tax revenue -> improve transit. nyc certainly benefited from aristocrats and lax labor laws when building the subway, but this isnt something that is impossible for portland. trimet is already huge for a city as small as portland. improving density will only help transit services.

it doesnt have to be subways -- the willamette flood plain isnt great for subways anyway. portland should continue to build out its bus service and cycling infrastructure. portland is already pretty reasonable for living without a car, it will only improve with density.
