KIA Motors review: passenger car lock - kia cerato

Passenger Car Lock Designed in a very weird way. I was at Kia Service Center and complain about the design of Passenger Car Lock. According to them, that is how the car is being designed. It is designed in a way that even if you centrally lock your car, you can still open it from inside the car without having to unlock it.
The design is so dangerous for kids. I never seen any car that has been designed in such a way. What would happen when you are driving and the kids simply open the door. Not to worry of the back door as there is a child lock but how about the passenger?
