I have just returned from my summer vacation in Turkey. I hired a stick shift car there and guess what? They drive on the wrong (
) side of the road, like you do in USA. Not a problem.
I used to live in Germany, same issue. Back then I used to own a right hand drive automatic and a left hand drive stick shift and used to swap between them without hassle. I have driven cars in USA many times in the past, when I used to be required to visit twice a year due to my work commitments. I once hired a car and they offered me a stick shift at a reduced rate because I was a Brit and no-one else wanted to hire it, presumably they thought I was used to them, and I was.
As far as I'm concerned, using the other hand to change gear isn't a big problem. It feels a little odd to begin with, but you very quickly get used to it. Because you sit in the middle of an Elio, it should feel less strange than with a four wheeler.
Only issue I had last week was my wife trying to get in the driver's door ahead of me when she had no intention of driving! Mind you, she often goes to the front door of the house ahead of me and stands in the way when she knows she doesn't have a key on her....
