With the Model 3 having such a clean look up front, I immediately nixed the idea of mounting my EZ Pass anywhere that it could spoil the view. At first, I did just place it way up front in the center, on top of the fabric, but that ended in disaster when the velcro hooks, attached to the transponder, hooked the fabric aggresively and pulled up some threads when I removed it. Don't repeat that mistake! I ended up mounting the transponder all the way forward on the glass roof, in the center, where it is never within view. Works like a charm.
