Clearly the Elio isn't a motorcycle. None of the three wheelers are. Only a side hack making a left hand turn can lean into the turn. I view the balancing of a motorcyle between the forces of gravity and centrifugal as central to the motorcycling experience. When cornering on a motorcycle, the sum vector of gravity and centrifugal forces keeps you one with the bike.
The Toyota iRoad, posted above, might come close, but in all conventional 3-wheelers centrifugal forces are going to force your body sideways in a turn, rather than down into your seat as on a motorcycle. This has to be true for trike conversions, the Polaris SlingShot, CanAm Spyder, etc.
For me, it is this aspect of motorcycling dynamics that is central to the experience, more than being out in the wind. Frankly, riding the K1200lt with helment, gloves, boots, AeroStitch, behind that great fairing and windscreen, isn't the "bugs in the teeth" motorcyling experience that so many Harley riders enjoy in helment free states. If you want open air, here's your motorcyle ride: a short sleeve, do-rag, no helmet putt-putt down the road. (I can't do that anymore, road rash scares the crap out of me.)
For handling, comfort, performance, luggage capacity, pillion comfort, sportability, there is still nothing as good as the BMW K1200LT. The GL1800 and the K1600GT(L) are fine offerings, but the K1200LT is still in a class by itself.
All that said, I want an Elio. Yeah, its a car. Front wheel drive. Heat and air conditioning. Airbags. Roll cage. No, it won't be as safe as driving a Hummer, vehicle safety isn't the main consideration here. The argument that I wouldn't have an Elio because it isn't as safe as a conventional car, but I do ride ride a motorcyle, is a pretty specious argument.
Why I find the Elio intriguing more than other three wheelers: Reportedly going to be cheap. Looks fun to drive. Sometimes when I'm planning on a quick outing, I can't be bothered with gearing up for a motorcycle. I am really hopeful that 2016 is going to be the year the Elio comes to market. I am watching with great interest and enthusiasm.
The Polaris Slingshot is rear wheel drive; imagine a single rear wheel drive in these conditions:
