Seattle
DT gets flooded at 1700 (5 PM) w/ 2.0x surges, but they're often short hops. Surges (if any) in Bellevue & Redmond during the same time are typically at much lower rates.
Are Eastside pax more likely to have longer rides home at this time of day--say, to Kirkland, Bothell, Issaquah, Renton...
