It's not a matter of being faithful. We understand (and so will model 3 owners , though the general concensus say they wont) I also think they will.. understand what Tesla is trying to do here. What they have accomplished so far is astonishing and anyone with any sort of work experience understands how hard that is, thats why we accept it and work together with them by being patient some times.
Faithful or understanding, same main point.
They know people will be patient and "work together", so they see no reason to spend extra money to improve service.
They can use that money to work on the 110 battery or AP 2.0. or Project 'Tritony Nine"
