BarracksSI and Longfemur are right that you don't generally turn the bar to steer on the road.
I do because I'm immature and like to go into tight spaces and off-road spots that I don't belong. I should have mentioned that before giving advice based on my preference. Most of my road riding is indeed more of a lean-to-turn deal. But I have a lot of fun goofing around, and prefer a flat bar to be able to get into those situations.

I had the pleasure of riding my friend's Cannondale R5 yesterday for a few miles. It was nice to duck out of the wind at speed and be able to change to several different hand positions. But it was worrisome to not have the brakes instantly at my finger tips. Something I hadn't considered about many new road bikes is that you can only shift and brake from the drop (edit - or hoods...Thanks BarracksSI). I'm used to my old Panasonic, which has multiple brake levers on the bars as well as shifters on the stem, so it doesn't really matter if I'm in the drop or not.

The steering was not much of an issue since it was just a long MUP ride. I didn't want to be a hooligan on someone else's bike, so I didn't really get into hairy situations where I needed to "steer." On my Panasonic, I've learned to not be stupid. On my mtb and Raleigh, I am afforded a little more forgiveness.

All in all, the R5 was an awesome ride, but 700x23c tires on a feather-light bike just don't seem to fit my riding personality. I get more speed than I need from the Raleigh hybrid, which is pretty much a "flat bar road bike" style of hybrid. Any roadie phases I go through are satisfied by the Panasonic.

I am, however, wanting a Kona Jake more and more as time passes. Go figure.
