There's an article on SF Gate about unequal parking enforcement in different areas of Oakland. A memo from senior parking enforcement supervisor Ronald Abernathy tells parking officers to give "courtesy notices" for parking on the sidewalk and parking in the wrong direction in Montclair and Broadway Terrace (AKA Upper Rockridge). Residents of East Oakland get a $40 to $100 ticket instead.
While there are some narrow streets in the hills that can require creative parking to keep the roads clear, other parts of Oakland have them, too (the article mentions Outlook Avenue which runs through Millsmont and Eastmont Hills.) Unequal enforcement of the parking regs is just wrong. Now that some parking officers have brought this to public attention, hopefully it'll get fixed quickly.
