Left turns are really bad!
Protected left turns slow down EVERYONE (transit, drivers, pedestrians) by increasing wait times. And unprotected lefts are unsafe for pedestrians and decease reliability for buses and drivers.

One of the little-known secrets of Zurich's transit priority and traffic management policies is that they systematically prohibit left turns to an extent that would never be accepted by a US DOT.
In these 4- and 5-way main intersections, not a single left-turn is allowed. So many such examples.
