At least it doesn't have the upgrade that first crossed my mind when I read that the back wings were for a future HMI. I was immediately reminded of the recent articles on HN about the potential for oxygen absorption thru the anus. This led me to think that a more useful upgrade for an HMI might involve an anal probe connected to an on-board oxygen generator to feed oxygen to the rider to help them stay alert. It seems like it would be useful on long cross-country trips. The wings could be retained as part of a deployable crash cocoon to envelope the rider so that they are buffered from the impacts of collision.

I did read in the comments that the range of this bike is probably pretty low so the functionality of the batteries would need to improve before this is practical for long-distance trips. In the absence of improved battery life, my upgrade would not be useful.

It is probably good that I don't design and build things for a living. Some ideas are not worth pursuing.

EDIT: I have thought of another advantage to the anal probe/oxygen generator. In the event of a non-fatal crash where the rider is injured but still has a heartbeat, the anal probe could function to supply continuous oxygen to the body preventing brain and organ damage as long as the oxygen generator functioned and the rider's heart was still beating. Hardening the oxygen generator should be important so that it is shielded from crash damage. This would also negate the need for resuscitation by mouth and in the event the rider's heart stopped, the anal probe could allow rescuers to focus on blood loss/circulation.

With that in mind it should be self-contained and detachable so that it could travel in an ambulance without needing to be removed. That would also make it possible to become a discreet accessory that you would put on (in) before mounting the bike and you could just wear it concealed as you shop, refuel, etc.

Maybe not such a hare-brained idea after all?

I think I read too much.
