Just an FYI, when Google Maps comes up with routes, there are penalties for complex maneuvers built in when ranking routes. An unprotected left will add a time penalty to the route option when it is ranked against alternatives. I understand what you are hoping for is a much harsher penalty (or maybe even a way to customize it completely), but wanted to point out that things like U-turns and other maneuvers are treated as penalties
