I am not sure what this entails. This has been done before and was shut down due to licensing issues. I hear that there are still some private bus lines out there. 

If they run a series of private bus line between Haredi cities, will they also be "mehadrin" in the sense of sending the women to the back of the bus? Will they be regulated? Can this be done cheaper than public bus lines that are partly subsidized by the government? Will they take rav kavs and qr codes or will it all be done by paying the driver, which has ben deemed dangerous and banned from public buses? I remember back in the good old days, with the private mehadrin buses you either had to pay someone in advance and sign up for a ride or someone would get on the bus at some point and take payment from passengers, rather than paying the driver. Maybe they would do this again.

If he can do it legally and make it work for cheaper, more power to him!

And if he can make it work, maybe it will indicate that it is time to end State-controlled public transportation. Maybe it will be time to privatize the entire thing, or at least as much as possible.
