Toll calculator in Maps app

Please tell me when toll calculations will be available in Apole Maps. I need this information when planning longer road trips, as I do not ordinarily carry cash, so I need to make special provisions to carry enough. It is not enough to have "avoid tolls" when plotting a trip, which is a major disadvantage of the app right now; enough of us are complaining about that inadequacy that I hope we stand some chance of having that rectified in the not-too-distant future. Somebody should be collating all the toll data published by all the various states and authorities -- what a coup for Apple Maps that would be.

We potential users need to be able to make decisions on the fly about what route to use by taking traffic, time on the road, gas consumption, and tolls into account. I bought Apple iPhone 5 and iPads running OS 7.1.2 -- smart devices -- to help me make these everyday decisions more intelligently, then I run up against a roadblock in this dumb app.

I do use the app now for local trips, and like the clear directions and reliability. But if I were outside my "stomping grounds" I would have no information about strategic alternatives for routes avoiding traffic congestion through various times of the day, finding gas stations (especially 24-hour stations along the interstates), and being prepared for tolls.

Can anyone tell me how often the traffic conditions on a planned route are updated, or whether it even happens after a set of directions is downloaded?

Lots of topics here. Glad for any info I can get.
