I do it often*.
The * is to denote that there's a reason - generally speaking the right lane is usually in far worse condition than the left lane. Mind you, I haven't lived in New York for about 4 years now, but winter sucks, and spring is actually even worse. Winters generally tear up the roads in NY, which is why there's actually only two seasons up there - Winter and Construction Season.
Thing is, just about any state I've driven in has similar issues - the difference being the farther south you go, the less often the roads are resurfaced. That means a lot of times pretty significant ruts in the road simply from travel, all the way to huge potholes. At best, they fill the potholes every year, but the surface is still horrible to drive on until they do a full resurface. The left lane is usually in far better condition.
Another thing is the pitch - down south with the generally heavier rain, the pitch of the right lane is far steeper than that of the left lane to facilitate water runoff. At these points I prefer to be in the left lane because I of a combination of the above - the water runs off to the right lane and usually pools in the ruts that have been left making controlling a vehicle in those lanes a far greater challenge, even at low speeds.
The main difference with me - I will move over if I know I'm not travelling at speed and it's safe to do so. I don't do it to be an asshole... I do it for my own safety.
