What is the value given to Telugu by AP govt?

Here I am saying the thing which I observed recently.
In Hyderabad I have observed that there are very less sign boards are written in Telugu. Even on the buses also less preference is given to Telugu in AP. Where as in Karnataka and Tamilnadu much preference is given to their mother tongues. If it continues to happen in future also this may be dangerous to Telugu. No need to hate or blame other languages.But Mother Tongue must be given much preference. On Garuda buses no telugu is seen.Why don't they write "Garuda" in Telugu on one side of the buses? Why don't they write the name boards in Telugu and in English as well?
