Vroom, vroom, vroom: I was driving south on 280 from San Francisco late this afternoon and found myself following an ultra-cool dark colored Tesla (I think it was dark green. Maybe black. Sort of but not exactly like the one above) with a piece of blue duct tape on the rear bumper. And, oh my, that car was flying. I was following him in my Prius, the official car of Santa Clara County, trying to see who was driving it (there aren’t a whole lot of them on the road so far) and before long I was doing 90, and he was pulling away.
