While this is true for much of Texas. I happen to live in a city that still has a public operator. So we just get more generalized flatter rates. I haven't looked into the details of my plan closely in a while as a result though, so you might be right.
En masse though, it seems not ideal from a cost perspective the way things have been scheduled up until now. I'll give them the benefit of the doubt that it might be adjusted better in the future.
