Even when they have a dedicated signal and plenty of time, I'm surprised at how terrible most drivers are at turning left (US/Canada perspective here). The standard approach seems to be, as soon as they enter the intersection, to point their car at the lane they're heading into, and then at the last second attempt to correct the fact that they're entering that lane diagonally. That usually means either cutting the corner of the oncoming lane or swerving into the adjacent lane/bike lane/shoulder (or both). This is easily remedied by proceeding straight into the intersection for roughly a car length before starting the turn. This lets you maintain a roughly constant turning radius and sets you up to enter the destination lane more or less straight-on. A bonus is that it's safer (it's easier to see people in the crosswalk) and more comfortable (than the sudden-jerk-at-the-end-of-the-turn that the typical maneuver requires).
