Good points.
I dunno enough about all the issues, but that general layout seems to have several examples (including from BMW and Suzuki). They're much bigger than the empty bike looks.  100 mph top speed is plenty. Presumably being able to stash battery cells almost anywhere would give more flexibility on the CG than having an IC engine. And the people wouldn't have to sit so high if a huge covered carrying capacity wasn't needed. But it will never handle like something like this...  ;-) An electric version of something like those Honda, Suzuki, or BMW scooters would seem to make a lot of sense for commuting in dense urban areas. A lot more sense than self-driving cars... ;-) Cheers, Scott.

PS.. re that top pic
Just CAN'T let that color-glossy sit there un-disparaged, y'know? Red-flag..
WRONG is:
Exactly (in height) ---> where this pair-of-butts sit:
-vs-
The C.G. of all the gearhead-bits, way-too-farbelow.. There; you are on STILTS!
Especially-awful with Two-Up. (Passenger if unskilled is dead-weight; cannot even Try to 'help'.)
Needs no words; The pic all-alone suggests well, the Difficulties a pilot Will endure/(or not survive)
with any need for a rapid maneuver.
(And look well at the height! of your boot-soles!) == lowest-point you Can place your body-weight to influence matters, i.e.
Because, also too the wheels are too-Small dia. for rest of chassis {sigh} Cornering demands here, as with a scooter, needs road-clearance == why they had-to place foot-rests ^where^ they did. :-/
You just *Can't!* use your body as you Need-to, to ameliorate [Your + machine's] combined C.G.
(thus to apply physics to S. Y. A.) {{sob}}
Rest case. Racer pic below: illustrates the shape-map for function: just torn-up by Boobus Marketus.
Std. Advertainment-pulchritude fantasy OVER all hard-won authentic-lore to date. Yeah they likely will peddle n of these. I hope to Drumpf voters (as would never notice 'science'.)
Just like glamorous Giant-'Hog' Ad-pix of Harleys, old Indian Chiefs ..with about same %mass given-over to sexy-sheet-metal cosmetic shapes
..as-in Detroit-iron of the days of Insolent/Heavy Chariots -vs- [all aspects of Basic design-physics]
You can get away with that in 4-wheelers.. sorta, but NOT with 2-wheel-equilibrium!
(I'd likely drive one of these around the block. Carefully. I drove a foot-clutch Harley.. Once.)

I don't understand those
They're not motorcycles. They aren't weatherproof. I can't think of a use case that something else isn't a better choice.

They're 3-wheel go-carts. For adults.

It is an opening
for those not/no longer comfortable on two wheels but for whom a convertible is too "square".
Trike conversions have existed for a very long time. Having the two wheels up front eliminates the differential problem and the Slingshot opens the market wider by having a steering wheel.

People still buy 'em.
BAC, Ariel and Caterham (and likely others) have four-wheel cars like that and they seem to be successful.
There was a memorably Top Gear challenge where the hosts got to use some of these cars in daily driving. Except it rained that day. :-)

Good points, but...
I envision them being used for commuting on urban interstates, 35 MPH roads, etc. Not tooling down the PCH or cutting through the Alps on a beautiful summer day. At least that is what I would use it for. The guy I saw on a red Honda version a few years ago must have been around 70. Energica EVA electric superbike. 617#, 124 mph top speed, 50-60 mile range when whooping it up, $35k+. :-/ It's got a ways to go yet. But it's good that people are trying! Cheers, Scott.
