I need a cab application

I need the programmer to add a function in your taxi script. Requirements of a special function in it: That comes customized with a function equal to Uber POOL (shared taxi) LInk video demonstrating [login to view URL] How did this Special function work? The function will have the name "Shared Taxi" in the administrative panel, and will be available automatically after the administrator creates a "new type of vehicle", where he will have the option to enable and disable this function. If the administrator activates this "shared taxi" function in one of the "Vehicle Types", the driver will automatically receive up to 4 travel requests at the same time as the UBER POOL. + In the Driver application: allow him to register in more than one "type of vehicle" and he can choose which "type of vehicle" he is going to use at that very moment of work. + In the driver and passenger application: After accepting the trip request, allow them to exchange messages between themselves as the UBER possesses, which resembles a chat within the app itself.
