I live in Northern Virginia (US) where we have a growing network of high occupancy toll (HOT) lanes paralleling existing roads. These come up as separate roads in Waze as they have their own on ramps and off ramps. Just to make them more fun, they have variable tolling so when traffic is more congested on the "free" lanes the toll lanes cost goes higher. The speed limit is also higher on the toll lanes so they always come out as preferred over the regular lanes for navigation.

The current Waze app allows selection to avoid or not avoid toll roads. This won't work for a commute like mine being that part of my drive goes on a regular toll road as the alternate route would take twice as long for the given segment of my drive. For the segment of my drive where the HOT lanes are present, there are cases when I would prefer to use those lanes being that if there is a major incident in the regular lanes the HOT lanes can save a considerable amount of time.

This could be addressed if Waze had an option such as "Prefer toll road if saves over threshold percent of time" where the percent can be set to a driver's preference. Best would be if this can be calculated on segments of the drive rather than just the entire drive. By calculating on segments the first part of my drive would stay on the toll road as that part would be over the set percentage if I took an alternate route. For the second part of my drive the navigation would be able to send me to the regular or HOT lanes based on traffic conditions.

Other's have suggested using cost based preference, using a toll road if it will cost under a set amount. This won't work for the HOT lanes because of their variable tolling when the cost to use the road can vary significantly throughout the day.
