I drive with two, I wish I could master the whole one hand resting somewhere else thing cos it looks cool. It's probably not a good idea for me at the moment with me being a very new driver. However if someone is in the car with me, then I drive with one hand as I'm one of those people that talks with their hands, so I'm forever taking my arms off the steering wheel. I love singing in my car too when I'm alone, it's the only time I get to do it.
