When the cops don't even respect the laws, the laws are meaningless.
Would you feel safe crossing the road now?
If it's something like 15 Av NW in Ballard, it's pretty obvious that you're meant to cross at a light, even if you legally have more of a right to cross at the uncontrolled intersection one block away. It's unreasonable to expect a highway-in-all-but-name to stop for one person when marked, lit crossings exist within five blocks at all points along the road.
Even in the case of normal 2 lane roads, drivers here still act like pedestrians do not have the right to cross anywhere but a crosswalk (and some don't even respect the crosswalk), and it only gets worse with 3 and 4 lane roads because that is where the drivers tend to drive significantly over the speed limit.
And yes, I do consider it reasonable to expect cars to stop for pedestrians in all scenarios where pedestrians have the right of way. A 5 block detour to cross the street can add another 15 minutes to your quick trip...what would happen if the situation were reversed? Can you imagine the outrage that would happen if cars had to drive 15 minutes out of their way? Slowing down for 5 seconds to let someone walk across the street is a miniscule inconvenience in comparison.
Preventing accidents isn't the only reason to enforce traffic laws.
