One thing about tutoring is that you have to do a lot of driving. I have become a super shortcut sleuth lately, avoiding construction, traffic abatement, and just ordinary congestion with lots of research and experimentation.
Above is the magical shortcut that gets you from Carthay Circle to Mar Vista during rush hour in only 15 minutes. It avoids both the purposely long red lights on Motor AND the single lane merge on National near Coop Pizza. And no this map doesn't go to and from anyone's exact house!
