Good question.
We excluded the "snow bikes" as usually the criteria was that it should be useable on a normal road (i.e. wheeled or tracked)
But this thing matches that criteria despite not being wheeled nor tracked

And how do we list this ? Is it a car, a motorcycle or boat? Noone can tell.

Bad click. Did first an "edit" instead of a "quote" to reopen the thread. And old posts cannot be deleted, even if modified later...

This one looks like a nightmare of Mater.
I don't know if it real or a good Gimp or Photoshop work nor if it really works if real, but I find it a little creepy...

It is taken from a short 3D animation movie. It is just a 3D (CG) object rendered over a background video layer.
The "Tractor-Spider-Crab" monster is a photorealistic digital character. Something of a whimsical agricultural urban nightmare, it actually looks more ominous and threatening than it really is. This hilarious mind-bending 3d animation was made by compositing a highly-detailed 3D animated model over actual video footage. The net result looks totally convincing and pricelessly funny.

Impressive, while "walking" in the street!
I'm sure it's a pal of Frank

Another one hard to categorize. Does it really fit the "tracked vehicle" class?
Meet the Tankchair : ("Tankchair is for outdoor use only because it is so powerful it can ruin carpet and walls..." - Liz Soden, the person for who the Tankchair was first made)
Made at first by a husband who wanted his wife to be able to continue to hike with him and their kids after an accident...
It has know a "sibling": the Speedster (motorcycle tires; speeds up to 30 mph...)
