Re: BIG FAT RESET BUTTON
First of all ... this issue isn't new. When was the last time you rented a car, that's bluetooth enabled? Ever tried to connect your phone.. and find others still in there?
So first and foremost, its the lazy people getting in these situations, that don't go through those apps and clear out their own data .. the last three cars I rented, I could have downloaded someone else's Phonebook data .. but being more of a white hat .. I simply deleted the other data from the system. They all have options to do so.
Second .. while I get Anon's idea.. it again imposes issues.. just like all of the other technological fixes for a horribly broken human existence.. Sure.. limit the reset to being at the dealer .. or manufacturer .. which means.. you *WILL* most likely have to PAY THEM to perform the service, even if its just to give you the code to do it yourself, while you are in *THEIR* parking lot, etc..
You think they won't? Look at all the american greed mongers that charge 75 dollars or more just to attach their Diag Tool to the modern car, to read what the car is saying is wrong .. and if you DONT pay it .. they hand it back to junior who sits there and futz around trying to figure out what's wrong, without using the Diag Data that should immediately move the technician to the troubled issue.
The simple fact, is 1st world problems, and educating people that this is an issue they must ensure for themselves doesn't happen for *THEIR* car, their sale of, or purchase ... that they make sure their first or last actions (depending on if you're the new owner, or the former) are to delete / wipe / reset via the option ALREADY PRESENT in the car and apps to do so.
