hi tom,
i am here to help, but you need to help me to help you. without more information, would be difficult to help you.
if it is just a matter of putting up a sign, i would not need to ask any more questions. i would leave you to sort it out yourself.
no, i do not work for google, or represent google in any way. i am a user, just like you.
but no one needs to work for google to get this fixed - as users, there are ways available to all of us to get this done.
as i alluded to earlier, a sign would fix this for you, and all of the residents of the 80 addressses. that is something all of you can do to fix it, that needs no other party's assistance, and for which no other party has any control and/or influence.
with a good sign, google maps can continue to direct to saddleback lane, and it would be nothing more than a small inconvenience for users.
if google maps suddenly disappeared from the face of the earth, does the problem disappear with it? is it reasonable to believe that another similar service that may be dominant in google maps' absence similarly route the same way?
you are asking for a solution (a) to a problem (b). this isn't a google maps only problem. it isn't necessarily unique to google maps.
but i understand - many use google maps, and fixing google maps helps tremendously, even if it does not fix the core problem permanently.
i can only help fix if you help me to help you.
