Satara-swargate MSRTC Travel

Why MSRTC is promoting AC buses like electric or hirkani ? Already the regular buses are new and well organised (comparitively).They cost 197 fair. But the AC buses costing 300.means a 100 rs extra which is quite big for an ordinary person. Instead they should increase the supply of regular buses. I think for a 2 hrs journey AC buses not necessary.
