Is this what you are driving? Then by all means, pull out to the right before you turn left, so that you do not destroy the lamppost, or kill pedestrians.
If what you are driving is more like this:
you can turn on a dime. From the Smart Car up to the mini-van, every car is quite capable of taking a 90-degree turn to either the right or to the left, with no swerve to the opposite direction required beforehand. This kind of driving is foolish and dangerous. If you are doing it, LEARN TO TURN properly.
