if you ever visit Portland make one up reading YOU HAVE THE RIGHT OF WAY. drivers keep it weird here by ignoring the rules of the road for some kind of "no no i insist, after you" as if theyre giving some gift, but instead just confuse everyone

if im biking and waiting at a stop sign: without fail, the last car in a long line of cars will slam on the breaks and insist i go when they have no stop sign. it would have been faster for everyone if they just kept driving and i cross after they pass, like the rules of the road prescribe

Defending that particular kind of driver: He might not have known to be the last car. But one thing he knows for sure: a long line of cars in front of him. Speeding up or keeping distance is pointless, so he uses that moment to be friendly instead.
