Northbound La Jolla Boulevard runs through a residential area just after Nautilus Street. So while it is the only major coastal thoroughfare into downtown La Jolla, the speed limit is only 25 miles an hour (standard for a residential area in CA). Most motorists don’t realize this even though it’s posted. Motorcycle cops will wait in the alley just before Genter St. and catch speeding motorists as they head into the downtown area. I haven’t received a ticket there, but I walk in the area and see them regularly pulling over motorist after motorist. It’s like shooting fish in a barrel.
