that sounds like a good idea, but im not to big on the magnetic field around the axle. I mean imagine putting that on a honda, the axles would snap easy. In that article yuo posted it said something about being able to move it forward if it had the power...what would stop them from having no tranny and no axles and just having one of these devices on the wheel hub and moving that back and forth? im sure they have already thought of that but still that would be tight.
