It was a one in 20 chance encounter. I felt like a paparazzi who got a chance to spy a celebrity but in this instance my camera caught a shot of the Tango, the car that makes look the Smart Car look like a Lincoln Continental. Only about 10-20 Tangos exists which makes the sighting more special. Actually my neighbor (a solar guy who already drives an EV-4) had the thing in his driveway in the Lower Haight and a crowd of passersby, tourists, and green auto enthusiasts formed around this electric only car.
As they say, looks can be deceiving. My neighbor said that the Tango can beat a Tesla in terms of acceleration. The Tango can accelerate from zero to over 130 mph in one gear. It accelerates from zero to 60 mph in about 4 seconds. We say Zoom to that.
