To give more history about this route, there is a annual "race the 8! event scheduled by seattle urbanists where people start off on the worst part of its route and do increasingly outlandish activities on foot while still beating it to its designations. Folks have beat it juggling, walking backwards, dancing, etc. Katie and her kids participated before she was the mayor, and you guessed it, beat it.
This route serves an intensely dense part of the city and has been failing people for years. The city/county have been making piddly, empty changes for nearly a decade that fixed nothing, like adding a 1 block bus lane. Yup, one block only.
The bus is regularly 30-40 minutes late, which makes using it miserable and unreliable. The reason its route is terrible is that there is a highway onramp thats right there near Amazon HQ. So for years and years people commuting in and out of the city have been prioritized over people who live in it, and no previous mayor had the stones to push back and fix it for actual residents.
