No, but I've always wanted to try. Ther closest I've come is playing around on my sliding/rolling see-saw. It's made up of a ramp, leading to a beam which sits freely on three cable spools sitting curvy side down. You ride up the ramp and onto the plank, then stop pedalling and do a mini stillstand until it passes it's fulcrum point and tips over, then you ride off. Very fun. I want to make one that slides further though, the furthest I got on a successful attempt was 1.5m metres of sliding before it tipped.

I've ridden in the subway as it stopped to demonstrate. Then the thing started moving. I wondered why I was pedalling so hard and leaning so far before I looked over and noticed the platform flying by. It was fun. ONce it evened out I started hopping and doing stillstands. I've also done it in the transbay tube on BART where the trains hit speeds around 80 mph. It's just like normal excapt a bit louder and bumpier, though.

I've unicycled on the car deck of a Washington State Ferry. The ferry is easy since it's so big that it doesn't rock or even feel like it's moving. I need to go out and find a more challenging moving vehicle to ride on.
If you had a really good driver of the vehicle, they could help you make adjustments to maintain balance. If you were falling backwards, they could slow down to help you back into a balanced position.
This might only work in theory. Adjustments would have to be pretty subtle by the driver. But it's fun to think about.
To go even heavier on the theoretical possibilities... You could sit on the uni and stay stiff while the driver makes all the adjustments for you. Just like balancing a pole on your hand or foot. The uni and rider would become like the pole and the vehicle driver would keep the rider upright. Being the rider for this scenario would be a weird feeling!
ive ridden on escalators, that was kinda strange..i also tried to sit at the bottom of one (going up) and pedal like it was a treadmill...didnt really work coz it wasnt going fast enuff. still stands were easy enuff

Well a MOPED or whatever you call it...yeah good one security
To go even heavier on the theoretical possibilities...
To take it still further, the driver could accelerate and decelerate the truck so that the rider rides forward and backward. By bumping the truck over speed bumps and the like, he could make the unicyclist hop up a cable spool or anything. Heck, if the rider has his feet on the pedals and provides power input, the drives has to 'compensate' for that. Anyone could do anything on a unicycle!
