TSLA will win
If you don't follow Roadster info, I understand, but Tesla has actually made a point to say they are supporting Roadsters. New accessories are going up on the Tesla website every few week lately. New upgrades coming include a racing motor. A battery pack is not out of the question then. (fingers crossed)
We heard several times (also from JB) about plans for an upgrade battery (and perhaps more, some larger yet expensive upgrade package. Though it wasn't clear how final they were. (Or not.)
