If you see three, its a thing.
Driving north near Pojaque, I saw a smart car going the other direction with a Yakima hitch mount rack with a dual suspension MTB on the back. It was cattywumpus on the rack with the rear wheel above the roofline of the car.
not a week later
Framebuilder and tiny car aficionado Curtis Retrotech Giantman Inglis himself seems to have this set up, seen on his flickr stream click for source.
A day after number 2:
This guy in my neighborhood has a homemade rack added to the factory hitch on his Smartcar. Factory hitch! Who wouldathunkit. Note the sweet lustron home in the background.
It is now officially a thing. All the rage. I am going to get a smartcar and festoon it with biketites screwed directly into the plasticky smartcar body and mount as many bikes as I can simultaneously so I can join the fun.
Also, Smartcar v. Bakfiets
From the comments, we received:

Thank you fellers! I knew it was a thing.
