2. If getting through downtown by bus is slow, getting through it by car isn't any faster.
Anyways, Seattle's transit problem isn't bad downtown bus service, it's godawful spoke-and-last-mile coverage, which eviscerates ridership, makes the overall network less efficient, and forms a negative-feedback-loop that blocks transit improvements.
Nobody likes sitting around for half an hour waiting for a bus that will take them to another bus.
