thanks to investment in public transportation, Seattle actually has less traffic than it did a decade ago, despite its growth in employment and housing.
According to the Seattle DOT Traffic Report (2015), Seattle added nearly 100,000 people in the decade from 2004-2014, while average daily car traffic in the city fell by some 60,000 trips over the same period. The travel demand created by population and job growth is being absorbed by the transit system
Yea... not so much. Going from Belltown to the interstate which is maybe 1 or 1.5 miles downtown,depending on how you go, can routinely take 30+ minutes. That's just to get out of downtown. The other 10 miles of my north bound commute takes about 20 minutes most days.
