Has anyone else had any luck with their 407 ETR (or similar) transponder on the Model S? I suspect my transponder is dead and have asked the 407 ETR to send me a new one. Speaking with customer service folks they do have a list of certain vehicles which have "metalized" windshields which means they will not work with the transponder. Based on the threads about the US EZ-Pass issues I'm wondering if the Tesla Model S needs to be added to that list.
