I am an argentinian Waze user, and it would be great to have voice notifications of road tolls ahead. In Argentina the prices may change between cars, motorbikes, trucks, etc. So the user will have to set up wich kind of vehicle is driving. The prices of the toll will be updated by users (exactly like gas station prices update).So, the main idea here is that your guiding voice will say you something like "Road Toll ahead, the toll price for car is $XXX". And of course, once Waze has all the toll information, when it calculates the route, Waze could show us the amount of money it will cost us to go to point A to point B.
Thank you!
