Sometimes its not possible to get the tag number as when they pass you going in the other direction. And often the color can be missed between dark blue, black and even dark green or RED (a little red humor there). Even though we don't get the color right or get the battery size, its still close enough I don't mean to hurt any feelings for the person that added those B.I. cars that don't show a tag number. But should we be counting cars that we can't make a distinction really exist; otherwise it can be counted twice? I believe the minimum to count a Tesla should be a license plate number. The color and battery size is just good details to help us understand the choices people make.
We know supercharging is enabled on 85's. But I suspect its a rare 60 in Hawaii that has supercharging enabled. Its going to be useful information for we owners to know how many Model S have supercharging enabled as we lobby for more charging locations.
