I haven't heard about those motors, but why would a low rpm motor not be good for cars? With a lower rpm motor, we might be able to get away with using minimal gearing, as long as there is enough torque to compensate. That would mean less wear on bearings since they aren't spinning so fast. The only downside I can think of for an outrunner is the fact that dirt might get into the openings, and you'd have to watch wire routing so nothing contacts the rotating can.
