The chain of responsibility pattern creates a chain of receiver objects for a request. This pattern decouples the sender and receiver of a request based on the type of request.

If one object cannot handle the request, it forwards it to the next recipient and so on. Maximum Passenger Capacity: Motorcycle:1 passenger, Car: 4 passengers, Medium bus: 27 to 34 passengers.

Chain: $this->next->Ride($nPassenger); Condition: the amount of passengers is greater than or equal to the initial passenger amount.
