For all who are worried about the 'burden' of having to get a cycle endorsement, I think with a little persuasion the rules will probably be changed in most if not all states, especially when the Elio becomes a fact of the road. The license and helmet laws will probably be changed. The trade-off, however, will likely be that the deffinition of a 'car' will be changed in the process to include the Elio, either by decree or de-facto change in regulation.
In other words, the motorcycle classification that provides so many nice loopholes will be void and this could cause all kinds of unintended consequences, not least of which is that the nice, cheap motorcycle insurance will not apply and we'll be paying for big-bucks car insurance instead. Changing laws will invariably result in ourr being fleeced for more money using any bogus excuse imaginable. I'd rather get a cycle endorsement, (If I didn't have one already), than pay thousands more for insurance any day. I would much rather keep the cycle license requirement 'cause that reinforces that the vehicle is indeed a 'cycle. Then take on the helmet thing as a single issue in which no one has a financial incentive, and it's an easy sell since requiring a helmet inside an enclosed vehicle IS just SILLY.
