@ragingloli I don’t think you get it. The system is junk and it will take time to fix. Charging full price based on what it takes to run a car and pay the driver to stop and start it is the best way to keep it moving. With far fewer riders and the cars being run safely they will be able to fix everything needed to that level of service and improve the speed and value of the ride. With good advertising of the improvements they will get more riders. Single cars can be run more often and provide fo greater convenience. Over time more and more cars could be hooked together. The subway system does have competition. It is getting more expensive to ride on the roads. With with the time for improvements and correct amount of money coming in the subway would be able to hold it’s prices the same or even lower them as it added more cars per driver.
This is really a trick question. It can only be answered by doing it and finding out what happens. Nobody can answer it by figuring out the right answer. That is simply not the way that answers to this kind of problem can be found.
It is an exercise in entrepreneurship.
