Roads are almost never flat. Pulling to the verge is normal, try driving it on the right. If it still pulls left get the tyres checked and tracking sorted. If it still pulls left get the brakes checked. If it still pulls left get it exorcised
I'm not clear what you mean about a dead spot on the rack but hydraulically assisted power steering often has some idiosyncrasies particularly at full lock.
