Tesla Roadster runs on batteries, and so too do (many) TAG Heuer watches. It's out of this obvious correlation that the TAG Heuer Tesla Roadster was born, a one-off special edition skinned in some unfortunate graphics then blessed with an extra slot in the center console for a similarly spendy Meridiist phone. There's also room in there for a one-fifth second analog Heuer Limited Edition Stopwatch, which sounds like a very useful addition indeed. Those attending Geneva Motor Show later this week will have a chance to see this (otherwise stock) car in-person, while the rest of us will have to make do with the gallery of photos below, which truly shows that "technology -- whether worn on your wrist or driven on the road -- can help us live better while we tread more lightly on this planet." These words courtesy of Elon Musk, who can surely be seen at the show wearing a giant piece of wrist-borne chronography.
