Is it possible to build & script a rickshaw/pedicab?

Someone I know is keen on having a pedicab/rickshaw built within SL -- I'm trying to think up ideas how it might be done, IF it can be done. What I'm talking about is something like this: http://www.manhattanrickshaw.com/insideimages/pedicab.jpg .

Would it be possible to have a "robot" driver programmed to take you around if you tell the driver directions?

Failing that, would it be possible to script simple animation of a robot driver pedaling a pedicab, while you point the direction, much as you do in a go-kart? (Or would that be too many prims?)

How difficult a proposition would this be? I am a designer, have some experience with scripting languages, but don't know LSL or how to build objects (yet).

Forgive my ignorance -- I'm a SL newbie. Just trying to get a sense of whether this is possible.

Any suggestions?

Thanks

Well the second idea seems most definitely possible. Although scripting an AI/BOT to take you around based on direction would be very difficult if you wanted it to avoid walls and follow streets.

That might help you if you plan on going ahead with this.

There's a dog sled out there that lets you attach an avatar to the front and another rides in the sled, same concept I would guess. Saw it at the Furnation Skymall I belive.
