This idea can implement in a district at first and then cover whole of city. all citizens can use of it but shareholders use of discount too. citizens can don't buy shares but if buy stocks then will get more discount too.
Dear My idea is new and wonderful and has not implement in any place in the world up to now but it is useful for any city exactly. we need to a sponsor and specially municipality must cover this project. I think it is doable for all cities as Indianapolis too. but we need to funding for implementing this project in Indianapolis. if government or municipality accept funding in this project then we can start it in Indianapolis. Also any citizen can buy other district's shares even if he/she does not live there. and all citizens can use of all of system of transportation even they donot buy their shares but please do consider that cost of their services are different for shareholders and others.
