BTW speaking of 50MPH arterial roads... This road is not quite arterial at this location... but it is a 50MPH road.
This road is marked at 50MPH just back a touch from where this picture was taken:
This is a single lane going each way, with a bike lane running beside it, with angled parking for beach access... and motorists typically wait in the BL for parking to open up; motorists also merge on and off just about anywhere... for parking. Now tell me it makes sense to have this road marked with a 50MPH speed limit.
What "rocket scientist" traffic engineer thought that 50MPH was appropriate for this road??? AND WHY?
This is the kind of idiotic "auto-centric" thinking that leads to motorist/cyclist/pedestrian issues.
