I have seen a few (local company).
Nice functioning design if you gotta have a trike.
Leno had the designer on his show, they are proud of them ow & I hate the front grille thing (personally) .
Don't like it, trikes, or Can-Ams. The Slingshots are kind of cool, but I think when the day comes that I can't handle a 2-wheeler any longer I'll buy myself a fast convertible sports car. My sister had a Freewheeler; I rode it and found no joy in it.
I have a buddy who just put a trike kit on his Heritage. He is in his 80's and finding it hard to handle a two wheeler. And at one time was a motor officer with the CHP.

Wife never cared for motorcycles, met her in '93. She told me she would ride if I got a three wheeler.
That never happened.
I took a TriGlide for a demo ride this past August. My wife won't ride on the back of a bike, I thought maybe she would go with me on a trike so I wanted to see just how bad they were. She still says she doesn't want to ride on the trike, But my point is I was very surprised at how much I liked the TriGlide. It's not the same as riding a Motorcycle but it is fun in it's own way and if that is what it would take to get my wife to join me on rides I would be at the dealership right now signing paperwork.
My wife has a Can-Am Spyder which I occasionally take for a spin. It's a fun ride, extremely stable, has ABS, Traction Control, and Stability Control. Has a G sensor so it can apply individual brakes to keep it wheels down in just about every condition.
