Wow!  Zero to sixty m.p.h. in twelve seconds is disappointing.  I wonder if it is so slow that it is dangerous?

Hardly dangerous due to lack of acceleration, but the only driven wheel riding an oily ridge while only one of the other two is in a rut creates terrible driving dynamics on poor roads, which we are only likely to see more of in the next decade.  I love tiny cars, but my test drive of a Solo was only marginally better than a Sparrow, convincing me that unless you're a ferry commuter, these 3-wheelers have no advantage over a good used i-MiEV, Fiat 500e, or Smart ED (in that order).

I'm curious here. I have an Arcimoto, and it feels stable. It's a tadpole design with both front wheels driven, (independently by 2 complete drivetrains, inverter through gearbox), and I haven't had any scary moments like that. I don't know if my time just hasn't come yet, or if different designs vary.
Jay got a back-seat ride at one point.
Any comments out there?

The Solo, like the Sparrow, is a tadpole with only the rear wheel powered.  Traction control is a problem for such designs, and if uncontrolled, centripetal precession turns the vehicle into a spinning top.  
John Lussmeyer had sEVeral "Sparrow spinouts" and might chime in.  
The Arcimoto 2WD design is superior for slippery conditions.  
My other comment was about rutted roads.  In a 3-wheeler, each wheel is on a different track, so you'll feel up to 50% more bumps compared to a 4-wheeler with only two tracks. The narrow wheelbase also means that only one tire of the three will reliably ride in a rut.  My narrow i-Miev is similar, but two wheels in one rut track straight and narrow.
The center of asphalt lanes tends to be higher and oilier than the two tire ruts, putting the vehicle at an awkward angle and setting up potential hydroplaning on that wheel in the rut, while the powered wheel is pushing on wet oil. 
That's what I meant...
