It's safer, less likely to produce any rage in other drivers and you also don't slow anybody down. I usually start as fast as the car for the starting of the turn, then move to it's side. If I were first, driver behind me might hesitate to drive parallel to me turning, but when I move over to the side of the car in front, it is when I'm sure it's safe and the others can just follow the car in front of them. That's been my experience so far at least.

Always ride in traffic, although bicycles aren't allowed to use car roads where there are separate bicycle lanes. The reason I chose to ride and find it safer in car roads is for another topic, but I'm happy to say that riding the way I do - no riders honk me, can't remember the last time anyone did. So I guess it's not bothering anyone too much. Just stay visible, predictable and get out of the way when It's safer/smarter, while taking the lane when that is the smart option.
