Geez, those would be decently sized streets if parking wasn't allowed on the curb, or at least not on both sides. But you have cars on both sides. I think it is amazing if that doesn't happen several times a day.
Similar to the city near me.. designed pre-personal vehicle age... now streets are way too narrow for everyone's personal "horseless carriage"
At least here, they allow parking on one side of the street only.. otherwise it would be impassable.
