Seattle traffic is beyond capacity. A stretch of I-5 (northbound and southbound) that usually takes around 5 minutes to drive through in light traffic now exceeds 20 minutes when all the commuter single-occupancy vehicles leave their gigs at 5PM. Wade it out until 7PM and it’s less terrible. The traffic focuses until, and dissipates after, one point: Mercer Street. Our new neighbor has invited all of their friends without the least bit of consideration for anyone else.
