Yes, I know.  You are right, it's hard to to conscious.  At first, for slow 
speed, I sat upright to be able to use my body movement, as I was used to.  
At speed, my slow, conscious operation of the bike's handlebar was fast 
enough to keep it sort-of in the right direction.

Probably.  I'm pretty good at hands-free.  I suppose learning to ride a 
motorcycle, where the body movement doesn't change the center of gravity 
much (the motorcycle is much heavier) helps to learn to ride a recumbent.
