Google is aware that it's a dead end: https://www.google.com/maps/dir/37.7855646,-122.4743446/37.7882646,-122.4746696/@37.7883098,-122.4758098,16.51z/data=!4m2!4m1!3e0 https://www.google.com/maps/dir/37.7855646,-122.4743446/37.7... The application of Occam's Razor that feels to me like the simplest explanation here is that Google is sending the cars into this dead end on purpose, and the unusual sign in the middle of the road seems like an obvious reason they may be doing it.
