Karnataka State Road Transport Corporation [KSRTC] — rash driving and hit and run

Ka 42 f 2009, registered as route number 44s, but changed to 47k has hit my vehicle and run today at around 6:15 pm on 12/06/2020. I was driving on the right side of the road and there was already a vehicle on the left side too, but he overtook in between and hit my vehicle and when asked to stop he ran away. Also spotted stopping in the middle of the road, where there was a bus stop. If the government vehicles are running on road in such a way, we can't expect much from ksrtc. Kindly deal with the driver who wasn't even apologetic. I had my mother sitting on the other end, who would take the responsibility if it would be a much serious accident?
