On page 9 of this presentation, in the "OEM Partner Study" they show a bunch of chassis originally considered for the Roadster including the K1 Attack, Ariel Atom (now Wrightspeed X1), and the Noble M12. The Noble M12 is this one: When I was driving up El Camino (past the MP Tesla store) a while back I saw a "badass" car parked in their parking lot, and recognized it as a Noble M12. It was in fact this one: At quick glance I thought it might be a Tesla with all sorts of wings added on. The license plate looked like "NO2SPED" which for a moment thought it meant that it had drivetrain 1.5 ("no 2 speed" transmission), then reality set in and I realized it was a "gasser" and "NO2SPED" was probably "ND2SPED" or something like that as an abbreviation for "Need To Speed". Some googling shows that the owner of the car owns "Need 2 Speed" indoor karting! OK, so I gotta give Boris a virtual high 5 here. He runs an electric go-kart track, owns an awesome Noble M12 and is apparently shopping for a Tesla! By the way, I had been dreaming of a bay area business opportunity for a while now (before knowing about "Need 2 Speed"), and since I don't think I will ever find the time & motivation to follow it up, I will toss it out here now: Since "SpeedRing" closed, the south peninsula could use a new indoor kart track, and it should be electric. No fumes indoors. No range issues as you are always near a charger. 100% torque at 0 RPMs is perfect there. Anyways, I had been dreaming of having such a placed called "eRacer". If someone else builds the place I would certainly be a customer!
