I'm not wearing a helmet. How can illegal information be sent to my father's mobile phone?

Maybe your father bought the car when he bought it. Your father registered his mobile phone number when he bought the car. A license plate corresponds to a person's ID card information, including mobile phone number information. This information is usually registered at the beginning of buying a car, so if you registered your father's ID card and mobile phone information when buying a car, it will be sent to your father's mobile phone when you use the car.
