Once in a while I check what's going on in the field of tilting vehicles, three-wheelers in particular. I realize that the Elio is a rigid three-wheeler. Here it is (patent pending). I'd love to hear what engineers have to say about this. It is typically a subject that would have been picked up by the FTR club by now. See my other thread about that club's demise.
