How do I change my vehicle type in Waze?

Waze can optimize your routes depending on what type of vehicle you are in by using data from other Waze users in similar vehicles. It doesn't seem like this would make too much of a difference in most situations, but you can try it out by opening Waze and tapping on the magnifying glass in the bottom left and then the gear in the top left to get to Settings. Then go to Navigation -> Vehicle Type and choose Taxi, Motorcycle or Electric.
