Your variability point extends beyond just left turns. Routes with lots of lights or that cross train tracks have extra variability. If I'm leaving with barely enough time I want directions that have low time variance since I cannot afford to be on the wrong side of the distribution. Other times I'm willing to risk some variance for a shorter expected time.
* On busy streets, left turns through uncontrolled intersections can have high variability. So you might be unlucky and get stuck for several minutes waiting to turn. A slower, but more predictable route might be better if you need to arrive on time.
* Left turns are simply more stressful than right turns. Saving a minute might not be worth the pain.
