BMTC Electric Bus
The electric bus introduced by BMTC had highly positive reviews, but they were unable to implement the idea due to the high cost of the bus (about 2.8 crores). I would like to suggest a model where some affluent section of the society here can donate the bus to BMTC(donate as in still have some kind of ownership of the bus).
For example, Sandlewood stars who can afford to can donate a bus and use the same bus to promote their upcoming movies as well(i.e poster of the movie painted on the bus). So we can have a Punith Rajkumar bus and a Sudeep bus all serving to save the environment and promote their movies.
