I don't think it is too late to fix this. Perhaps Tesla Motors could reconsider and backup a bit. It is never too late to say, "oops, sorry we weren't thinking this through logically because of the rush going on at the Detroit Auto Show. Here is the fix."
I certainly wish this would be the case, but I have very little hope of it short of TM being forced into it by legal action. I have followed every public detail of this company since the beginning. I have heard Elon speak a number of times. I can not recall ever hearing or reading of Elon admitting that he made a mistake. The blame has always been placed on someone else. This action was initiated by Elon in the form of two emails from him. It would be very hard for him to not accept responsibility for this fiasco
