I travel in an area where HOV lanes are prevalent (VA/MD/DC) and make frequent cross country trips. It would be nice to add trip details like using HOVs, have an EZPass (So the app can direct to those specific lanes - think entering NYC), number of passengers, etc. This way when traveling the app can direct you to those lanes. This would be especially helpful when traveling in unfamiliar areas or if uncertain if your type of pass will work with that toll system.
Currently the client (the phone application) does not have the capabilities to know what you are (HOV,Truck, Bus, Bike, or have a EZPass). So everything is setup for a private vehicle and the roads are setup to indicate if a Toll is needed (remember we have no means to tell you what type (Cash,EZPassā¦)
So until Waze gives the client more setting/options, Waze will route you the best route possible (and will indicate if a toll is required (if you have that option turned on to allow toll roads)).
