Ahh, so you are doing the reverse commute. I was hoping that you had a passenger to make this a bit safer when driving.
As you say you are the edge case. Waze is doing what it is designed to do, which is find the fastest route. The problem is that you are finding the toll excessive. Waze did finally recently add the option to avoid tolls for those that don't want to pay for the fastest route. However, there is no mechanism to indicate that you are willing to pay some tolls and not other tolls. And given the dynamic pricing of the express lanes, I'm not expecting a solution to this issue anytime in the foreseeable future.
All that being said, I'm still curious why you consistently get a recalculation to the express lanes when you are being routed in 123 or 66. When you first ask for route at your departure point, is waze's first choice to route you via 123 or 66?
